I'm confused about optical low pass filters (found on CCD imaging devices). As I understand it is a double layer of birefringent material which in effect splits light into 4: (2*25%) green, 25% red, and 25% blue (for a standard bayer matrix). The part I'm not sure about is if all 4 fall on the same CCD element, or if they are directed to 1 element each.
If the latter, are the 4 computationally combined as a pixel?
