The Walsh transformation has been experimentally carried out with coherent optical system. A five-plane coherent transformation device is designed, 1 - dimensional 8-sequence Walsh transformation is realized, the Walsh transform-spectrum is given. This design may be applied in principle to two-dimensional Walsh transformation.
