摘要：
A novel compact optical correlator with a short optical-path system and fold mechanical structure for pattern recognition was introduced. Experiment shows that the optimized design of match spatial filter by means of Monte Carlo iteration algorithm can increase the signal to noise ratio of correlative output plane and correlative peak value, so that the accuracy of pattern recognition is improved.
