Target recognition by using opto-electronic joint transform correlator

This paper uses opto-electronic joint transform correlation method, and design a computer optical information processing system by applying up-to-date write-read device-electrically addressed liquid crystal device (EALCD) and charge-coupled device (CCD). By utilizing optical-correlation detection method, we can realize real-time detection, automatic recognition and high-precision location of objects. By processing all sample spots simultaneously, the processing speed can be improved highly. We can also improve the SNR of system with all kinds of digital image processing technology and output the correlation signal. Then we can precisely detect and real-time recognize the position of target in the space.
