提出了一种时序循环级联式的子波变换相关识别系统。该系统是基于循环使用一个普通光学相关器，而相关器采用光折变全息图作为空间匹配滤波器，一个受计算机控制的空间光调制器作为输入器件，方位不同的参考光用于编码存储不同的输入信号、不同的子波和子波变换的傅里叶谱的多重信息。通过计算机控制系统互连网络和级联循环次数可完成用于不同目的的相关运算。给出简要的原理分析，并用纯光学方法实验研究了Ｈａａｒ子波变换、Ｈａａｒ子波变换相关识别，并与普通相关识别作了对比。讨论了该系统所具有的诸多方面的特点 A time series loop cascade wavelet transform correlated recognition system is proposed. The system is based on recycling an ordinary optical correlator, while the correlator uses a photorefractive hologram as a spatial matched filter, a computer-controlled spatial light modulator as an input device, and different azimuth references for encoding and storing different The input signal, the different wavelet and Fourier transform Fourier transform multiple information. Through the computer control system interconnection network and the number of cascading cycles can be completed for different purposes related to computing. A brief theoretical analysis is given. The pure optical method is used to study the correlation between Haar wavelet transform and Haar wavelet transform, and compared with common correlation. Discusses the system has many aspects of the characteristics
