Abstract： Based on the configuration of coherent optical system composed of a holographic mask and two Fourier transform lenses, an approach of performing a 2-dimensional (2-D) linear transform is suggested. The 2-D Walsh-Hadamard transform of order 32 is tested, and the experimental results are given.
