OPTICAL PROCESSING APPARATUS USING RETROREFLECTION

This abstract first appeared for US patent application 18761991 titled 'OPTICAL PROCESSING APPARATUS USING RETROREFLECTION

Original Abstract Submitted

Provided is an optical processing apparatus including a light source configured to generate light, a first spatial light modulator provided on a reference plate and configured to modulate light, a first retroreflective lens provided over the first spatial light modulator and configured to perform optical Fourier transform on the light, a second spatial light modulator provided adjacent to the first spatial light modulator on the reference plate and configured to receive the light from the first retroreflective lens to re-modulate the light, a second retroreflective lens provided over the second spatial light modulator and configured to perform optical inverse Fourier transform on the light, and an optical detector provided adjacent to the second spatial light modulator on the reference plate and configured to receive the light from the second retroreflective lens to acquire an image detection signal.
