Abstract

Optical phase correlation calculation can achieve high-speed, passive, high signal-to-noise ratio target detection. This paper proposes and demonstrates a one-dimensional information parallel comparison system based on an optical correlator. The system uses 4-f optical architecture as the basic device and combines multiple optical structures such as beam shaping, wavefront phase modulation, and optical phase correlation calculation to achieve the parallel computing function with one-dimensional information as the main detection object, and the feasibility of the comparison calculation is verified by simulation. The detection system based on optical correlation proposed in this paper has potential application value in the field of genetic detection and matching.
