Abstract

We have developed a completely new type of optical antialiasing filter that offers both high performance and low cost. This type of filter can sufficiently attenuate all spatial frequencies beyond the CCD detector bandlimit. Antialiasing filters currently in use typically just null out very narrow bands of spatial frequencies.
