Abstract

We have proposed and studied the synthesis of the optical coherence function by utilizing direct frequency modulation of a laser diode[1-4]. We applied this manner to 2-dimensional (2-D) or 3-D optical information processing systems[3,4]. It has the optical processing functions, such as a slice extraction of an arbitrary depth from a 3-D semitransparent object. In this information processing system, holography is used to choose the interference component selectively from other components. Use of a silver-halide hologram has prevented real-time processing in our previous study[3,4]. In this presentation, we demonstrate real-time processing by using a liquid crystal spatial light modulator as a real-time hologram.
