An optical implementation of a wavelet transform is presented. Optical Haar wavelets are created by the use of computer-generated holography. Two different holographic techniques are explored: (1) interferogram and (2) detour-phase. A discrete representation of a continuous wavelet transform is obtained by the optical correlation of an image with a Haar mother wavelet. Experimental results are compared with their digital simulations.
提出了一种小波变换的光学实现方法。通过计算机生成全息术创建光学哈尔小波。探索了两种不同的全息技术:(1)干涉图和(2)迂回相位。通过图像与哈尔母小波的光学相关获得连续小波变换的离散表示。将实验结果与其数字模拟进行了比较。
