Abstract

This paper presents the spatial-frequency responses of various photodetector-array patterns. It discusses modern photodetector arrays: those having a Bayer pattern, multilayer structures, and composite authoring systems. The last combine spatial color separation with multilayer cells into which IR-sensitive layers are introduced. A comparative analysis of the spatial-frequency responses of color photoarrays showed that composite-system-based patterns have better spatial resolution and higher spatial (contrast) sensitivity than a Bayer pattern. Multilayer systems showed the best result in the comparison. Composite authoring systems also showed that these designs were promising. Calculations are presented as evidence, along with spatial-frequency-response curves of various systems.
