Nikon Stacked CMOS Sensor Will do 1000fps in 4k!

Leave a comment
Nikon Stacked CMOS Sensor

Nikon Japan has been busy creating the next generation of 1″ stacked sensors.  The latest is a 17.84 Megapixel stacked design with hyper-fast memory interconnect that shoots up to 1000fps at 4k resolution which is no slouch. The sensor is still in development but it will be a possibility to see it in a camera that could compete head to head with the Sony RX series which now dominate prosumer P&S sales.  It was announced at ISSCC (International Solid-State Circuits Conference) held in San Francisco, February 15, 2021.

The sensor works by shooting in buckets of 16 x 16 pixels as one block, and then subsequently 264 x 264 pixel blocks (4224 x 4224 pixels) are conformed to form the final image at nearly 18MP.  It is unclear at this time if 4k video will be a windowed resolution or a supersampled then reduced final image from the full sensor.  The market for this sensor goes beyond consumer cameras as it is aimed at other applications like self-driving cars and production lines. → Continue Reading Full Post ←

Phantom Slow Motion Camera Used to Study Coughing Reach!

Leave a comment

Phantom Slow Motion Camera

Schlieren Imaging has always been a very narrow and specialized field of imaging. It can visualize air perturbations in a fluid-like way that can show the reach in this case of someone’s breath and heat dissipation to see if a mask makes a large enough difference in transmission of infected airborne particles compared to no covering.

By using a Phantom VEO4k 990 slow motion camera at 938fps and a speckled background with specialized angled lighting, researchers were able to test a variety of masks while coughing to see the effects.  You can watch the video posted here and also check out the full study available here if you want to dig deeper. → Continue Reading Full Post ←

100 Million fps High Speed Camera Developed to Fight Cancers!

Leave a comment

100 Million fps High Speed Camera

The Rosalind Franklin Institute  has started the development of a 100 million fps high-speed camera that will operate at 1-megapixel resolution to scan how new cancer drug treatments along with ultrasound interact to create effective cures for the deadliest forms of the disease.   This type of performance is unheard of in that resolution and would herald a new way of looking at minute amounts of time that happen so fast no detector so far has been able to capture them at a usable resolution.

To put this in numbers, the camera will be able to capture a 100,000,000,000,000 or One Hundred Trillion Pixels per second or one hundred million megapixels/sec. Those are staggering numbers and if saved in a raw format it would take a megabyte per frame or 100 Terabytes of imaging data/second.  That will be one extremely large frame buffer. With compression techniques and image optimization you could probably get that number lower but if played back at 30fps it would take 38 days to see a single 1-second video, staggering speed for sure!

100 Million fps High Speed Camera Press Release is Below:

WORLD’S BEST VIDEO CAMERA TO DEVELOP CURES FOR DEADLIEST CANCERS

The Rosalind Franklin Institute (RFI) today launched an ambitious new project to build the world’s most advanced real-time high-speed video camera, the key to understanding new techniques that use light and sound to treat some of the most lethal forms of cancer. 

Business Secretary Greg Clark today launched the Rosalind Franklin Institute and announced its first major projects including funding to develop the World’s best ultra-fast video camera for imaging tissue with greater sensitivity and at higher resolution than any other instrument currently available.

The camera will be invaluable in developing new techniques that use sound and light for both detecting and treating disease, including some of the most lethal forms of cancer such as pancreatic and brain tumours, with minimal side effects for patients.

The new instrument will be developed through a collaboration between an academic team at the University of Oxford and a UK-SME specialising in high-speed imaging, Invisible Vision. Once completed it will be housed at the new Rosalind Franklin Institute being built at the Harwell Research Complex in Oxfordshire for use by researchers in the UK and the rest of the world.

Chemotherapy is one of the most common treatments for cancer, using powerful drugs to kill cancer cells or stop them from growing and spreading to other parts of the body. These drugs are introduced into the bloodstream and absorbed into the surrounding tissue.

 Professor Eleanor Stride from the University of Oxford, said:

“A major challenge with current delivery methods for cancer drugs is that they rely on the active molecules reaching and entering the tumour cells by diffusion. This makes it difficult to ensure that all parts of a tumour are treated and leads to terrible side effects because large volumes of healthy tissue also absorb the drug. We need to find a better way to get these drugs into cancer cells specifically, quickly and effectively.”

Professor Stride said:

“The approach we’re developing introduces harmless particles into the bloodstream and then uses ultrasound to activate them, in order to both release the drug at a specific site and helping to drive it into the tumour to reach all of the cells within in it.”

The new instrument will be a key part of the core capability of the RFI’s INSIGHT (imaging with light and sound) theme, which will be devoted to developing technology for imaging and therapy at the intersection of light and sound.

It will be the first camera in the world able to capture up to 100 million individual frames per second at 1 megapixel resolution and operate across a wide optical spectrum from ultraviolet to infrared. This one-of-a-kind camera will enable researchers to see how ultrasound interacts with drug-loaded particles and tissue and how that enables controlled the uptake of drugs into cancer cells. The camera will help researchers to understand the biophysical mechanisms behind drug delivery – critical to perfecting ultrasound targeted drug delivery.

Professor Stride continued:

“Most current devices are limited to the optical part of the spectrum or look at specific wavelengths. This camera will be flexible, able to look at the full spectrum from ultraviolet to infrared, which means we’ll be able to see more detail and get higher resolution images than ever before. It will help us see how the ultrasound affects the particles and how exactly it helps improve the drug delivery and allow us to develop the treatment to make it more effective.”

Currently, the fastest long record duration framing camera in the world best suited for these applications are still mechanical, operating at speeds up to 25 million frames per second. The new camera will be smaller and more compact (looking similar to a conventional video camera). It will be faster, more sensitive, and give higher resolution real-time imaging than any other device available today.

Once completed, the new instrument can be configured in a variety of ways and applied to broad range of problems in materials science, plasma/shock physics, combustion, sonochemistry, photoacoustics, biological membrane dynamics and fluid dynamics. It will produce exceptional images of the interaction of ultrasound with tissue and provide fundamental scientific insights that could lead to important new discoveries.

Underwater Slow Motion on Lumix GH5!

Underwater Slow Motion on Lumix GH5

The Youtube channel Backscatter has posted a glowing review of the Panasonic Lumix GH5 for underwater shooting. The camera is a favorite of low budget film makers and those looking for the utmost quality with 10 bit color in a small package.  The Backscatter review also points out that the slow motion feature of up to 180fps in Full HD works really well underwater.

We, however, recommend you stay at 120fps full HD to avoid some artifacts like moire and aliasing which the at 180fps show up easily and at 150fps are there to a lower degree. The GH5 can white-balance under water and does a stellar job at different depths according to the review.

There a re a couple of dome underwater housings for the GH5 released in the past couple of months that allow for easy all button operation for scuba imaging enthusiasts.  The small footprint of the camera and the pristine image quality it can deliver at 4k from 6k supersampling even at 60fps 4k make the camera an excellent alternative to Arri Alexa and RED Epic/Dragon cinema camera rigs.

Panasonic GH5 – Underwater Camera Review by Backscatter:

The video above has both 4k 60p and 1080p 180fps samples for you to see the camera in under-water slow motion action.  The in camera sensor stabilization is also so good underwater that the footage looks rock solid from the review samples.  It is quite amazing what you can get today for under $5k USD as an underwater kit. Just a decade ago you would get half the quality and much less freedom in frame-rates for 20k worth of heavy gear.

The full written review about the GH5 and the underwater cases can be found at the backscatter official website. Including extra review footage!

Schlieren Imaging Slow Motion DIY!

Schlieren Imaging Slow Motion

Sometimes all it takes to embark on a new project is some unexpected inspiration.  On the Incredible Slow Motion video by Veritasium – Seeing the Invisible: Schlieren Imaging in SLOW MOTION we are not only inspired but awestruck by the results of this simple and doable at home scientific experiment.   The experiment allows a camera to visualize the vortexes of gases and temperature differences in the air which serve to create some very interesting scientific experiments and or artistic visualizations.

You will need a Concave Parabolic Mirror like the ones used in reflective Newtonian telescopes, “you may have one lying around from your stargazing days”,  you will also need a small light source like an LED flashlight or single diode and finally a razor blade or similar precise object to cut off the light to the camera on a plane.

The video by Derek Muller goes into good detail about how to prepare your lab experiment and while you may need to tweak it several hundred times to get the best results it should be ready for experimentation without much fuzz and you should be able to try dozens of setups to shoot. Here is a site that helps you make your setup as well!

Seeing the Invisible: Schlieren Imaging in SLOW MOTION by Veritasium:

Schlieren Imaging Slow Motion:

Using a slow motion camera will also allow you to better appreciate the intricate patterns and disturbances in the air at room temperature like your breath or the cool air emanating from a beverage.  Using a small candle in front of the mirror could help you in setting up the experiment so you can tweak and look at your camera’s LCD monitor to perfect the positioning of the setup.

It is of note also that you will need a long lens to zoom into the mirror area and get the coverage of the shot you want.  Cameras that have long reach or interchangeable lenses and do good slow motion are plentiful like the Sony RX10 series ,Panasonic GH5, edgertronic, Chronos 1.4 and Sony a6500.

=&0=& (from German; singular “Schliere”, meaning “streak”) are optical inhomogeneities in transparent material not necessarily visible to the human eye. Schlieren physics developed out of the need to produce high-quality lenses devoid of these inhomogeneities. These inhomogeneities are localized differences in optical path length that cause light deviation. This light deviation can produce localized brightening, darkening, or even color changes in an image, depending on which way the ray deviates. First observed by Robert Hooke FRS !
