Optical Anti-Aliasing Filters

In an electro-optical imager, a readout device (e.g., CCD or vidicon) samples an image discretely. Often the sampling spatial frequency is much less than the Nyquist rate for the system optics. Scene clutter at higher spatial frequencies that the readout passband is aliased into the band, giving exc...
