Paper Abstract

In contrast to imaging and interconnect applications, which require fixed diffractive optical elements, applications such as optical image processing and target recognition require diffractive elements that can be altered dynamically in real-time and, therefore, require the use of spatial light modulators (SLMs). Present SLM technology, however, has limited spatial resolution and space-bandwidth which affects system performance. We present techniques for designing diffractive filters for display on SLMs in coherent and incoherent image processing systems. Laboratory results are presented for a coherent matched filter design for display on a binary phase SLM.
