Abstract
A computer-generated binary amplitude-compensated matched filter is proposed. The filter has only a few discrete gray levels. As compared with the filters made by the optical method, the performance of filters made by computer-generated holography appears no worse, and fewer discrete gray levels are obtained; it is compatible with an e-beam lithography or an amplitude-modulated spatial light modulator. The excellent performance in discrimination and in Horner efficiency of the amplitude-compensated matched filter is preserved. The circular harmonic version of the amplitude-compensated matched filter is also investigated.
