Talking about sensors, have a look at this:
sCMOS - The online home of Scientific CMOS technology
Scientific CMOS.
5,5 Megapixels (2560(h) x 2160(v)) (And i hope they dont plan to increase much).
Readout noise: < 2 e- rms @ 30 fps; < 3 e- rms @ 100 fps
Maximum fps: 105 fps for rolling shutter and 52.5 fps for global shutter
Pixel pitch 6,5 μm
Dynamic range > 16 000 : 1 (at 30 fps) (approx 84 dB).
Maximum quantum efficiency: 60% (With excellent red and near infra-red response).
To compare, high grade full frame (sensor type not format) CCD:
Kodak KAF-6303 6.3 MP 3088 x 2056 9.0um 33.4mm diagonal 0.6fps:
Quantum efficiency: 40%, 52%, 65% (depending on manufacturing).
Readout noise: 15 electrons rms
Dynamic range: 76 dB (~6310:1) NOTE: Its not directly linked to saturation brightness but min:max value, you can increase theoretical DR by decreasing noise.
Maximum data rate: 10 MHz (0.6 fps).
But i dont think that those are that kind of sensors that are being used in cameras. unfortunately.
