RGB camera sensors can't identify specific wavelengths, all they can tell you is that a given wavelength is in some specific range. And when the light is not monochromatic then it becomes impossible to determine the spectral pattern.
- Gibbon1 11y agoI think these sensors implement n color vision, working a lot like the ear does. Instead of just detecting three colors you detect hundreds of colors. With each dot tuned to a fairly narrow band of light you get good selectivity.
- CamperBob2 11y agoRight, I'm just wondering how many discrete sensors you need before you can say you have a "real" monochromator. This scheme appears to work a lot like an RGB sensor, but with more than three filters.
