Optical anti aliasing filter

WebAnti-aliasing filters are used with discrete time sampled electronic systems to prevent signal spectrum foldover (Figure 1). The filters reduce spurious signals due to aliasing and reduce the bandwidth of the noise. Optical systems with electronic readout typically sample in one dimension (e.g., raster or pushbroom scanning) or two dimensions ...
