Optical Spatial Frequency Filtering of Image Sensors ?

The Kodak paper cited two factors: efficiency within the pixel is greatest close to the electrode; and color cross-talk. Basically, the detector with the Mosaic filter is deep. Light coming in close to Nadir will stay within a single element of the mosaic filter and will be focused close to the electrode. Light coming in at a steep angle can cross from one element of the mosaic filter into another, can come in at a shallow angle into the detector element and not be fully absorbed.

Color artifacts occur mostly due to interpolation errors for the demosaicing process. I can use a 60 year old Jupiter-3 stopped down to F2.8 and get color artifacts on the M8 and M9. Once you resolve past 36 LP/mm the resolution of the Bayer 2x2 site is exceeded, but absolute resolution of the sensor is not exceeded until 72LP/mm. This will not be a problem for the M Monochrom. I'm not going to compute Voigt profiles. Used to do that in the 1970s for overlaying modeled imagery over experimentally generated imagery.
