Abstract

In the recording system, the image of the external object that is converted to a coherent replica by the O-SLM is recorded on the medium through a holographic optical system. The authors have developed a high-speed SLM using ferroelectric liquid crystal called a bipolar-operational SLM (BSLM) that offers a high potential transfer bandwidth of about 10 Gbits/s. The BSLM is capable of accepting the images of external objects even in gray-scale, latching them and displaying the outputs reversibly. This parallel accessing memory system eliminates the bottleneck between memory and the parallel optical processor and will be useful for image processing and pattern recognition.
