摘要: By combining a lenslet array with masks it is possible to obtain noncoherent optical processor capable of computing in parallel generalized 2-D discrete linear transformations. We present here an analysis such processors (LAP). The effect several errors, including aberrations, diffraction, vignetting, and geometrical mask are calculated, guidelines design LAP derived. Using these results, both ultimate practical performances compared those competing techniques.
