A two-dimensional wavelet transform is optically performed in real time by use of a new multichannel system that processes the different daughter wavelets separately. The system, which is able to handle every wavelet function, relies on a Dammann grating for generating a multichannel array. All channels are processed in parallel by a conventional two-dimensional correlator. Experimental results applying Morlet-wavelet decomposition are presented.
利用一种新的多通道系统实时光学执行二维小波变换,该系统分别处理不同的子小波。该系统能够处理每个小波函数,它依靠一个达曼光栅来生成多通道阵列。所有通道由一个传统的二维相关器并行处理。给出了应用莫雷小波分解的实验结果。
