本文通过光电混合联合变换相关的方法,应用国内外最新的写入读出器件——电寻址液晶和电荷耦合器件、光学信息处理系统、计算机处理系统,利用光学相关探测方法,对目标实现实时探测,可自动识别及高精度的对目标进行定位。由于光学相关是所有采样点并行处理,这样就可以提高处理速度,并能用各种数字处理技术提高系统的信噪比,并输出相关信号,可以精确的探测和实时识别目标在空间的方位。

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 realtime 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.
