Abstract

A coherent optical system for performing an arbitrary linear transform is described. The system consists of a holographic mask and two Fourier lenses. A set of equations for determining the amplitude-phase distribution of the mask is given, and the mask is generated by combination of a computer-generated hologram and optical holography. As an example, a Walsh-Hadamard transform of order 32 is realized.<>

用于进行光学变换的相干系统

描述了一种用于进行任意线性变换的相干光学系统。该系统由一个全息掩模和两个傅立叶透镜组成。给出了一套确定掩模幅相分布的方程，并将计算机全息图与光学全息相结合来生成掩模。作为一个例子，实现了一个32阶的Walsh-Hadamard变换。
