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.<>
