Highly integrated compact optical correlators using FLC-VLSI spatial light modulators and diffractive optics

Due to advances in spatial light modulator technology and high-speed imagers, optical correlators are becoming viable for a variety of high-speed image processing applications. However, conventional approaches to assembling correlators produce systems which are costly to manufacture, and which are too large for some uses. We are investigating approaches to the construction of compact, highly integrated correlators that combine ferroelectric liquid-crystal-on- VLSI spatial light modulators, a CMOS imager, and diffractive optical elements.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.
