High Dynamic Camera Records SLS Rocket of NASA'S Test

First off, we would like to thank everyone for the positive responses! For anyone interested, our company, Innovative Imaging and Research, is developing this technology with NASA. This technology generates high speed high dynamic range imagery for monitoring rocket propulsion testing.Amazing to see. How does the sensor generate such a high dynamic range? I saw a pamphlet that said it was an on chip solution. Does it use differing gain on individual pixels, or is it some sort of other method? (assuming you're allowed to talk about it)

Can you give a brief'ish explanation the tech which makes the increased dynamic range possible, and what things are tweaked to adjust the dynamic range? It only speaks to it briefly and without expanding on it in the article, but mentions changes the team made to compensate for the increased dynamic range of a full-scale plume brightness, and also suggests more dynamic range coverage in a second iteration of the camera.

The HiDyRS-X project will design and build a novel, state-of-the-art, high-speed video recording system to provide 3-D HDR video for operational use on the SSC rocket en- gine test stands, which is “game changing” from a videography perspective. This is because HDR imaging acquires multiple images at di erent exposures and applies digital signal processing algorithms to recombine them into a single image that excludes over- and underexposed pixels to improve image quality. The result is an image with more detail than could be cap- tured by a single exposure. HDR imaging effectively increases a camera’s dynamic range and eliminates saturation. Typically, HDR images are developed us- ing multiple cameras or multiple exposure sequencing.

Well the Navier Stokes equations aren't really a simplification. To our knowledge they completely describe fluid flow (barring anything like charge interaction, etc. Even so those interactions can be built in). The Millennium Prize is to prove that an analytical solution to the NS equations always exists. The proof also does not have to be constructive. You just have to prove a solution exists in all situations, not actually demonstrate what that solution is. The constructive proof is even harder.
