Abstract
A new spatial filter, the quantized amplitude compensated matched filter is proposed. It is characterized as amplitude modulation only with several discrete grey levels. As compared with the amplitude-compensated matched filter, the Horner efficiency is quite poor. However, the high discrimination is preserved, and an amplitude-modulated spatial light modulator might be accommodated. The circular harmonic version of this filter is also investigated.
