Abstract

The paper suggests a method of computation of Discrete Walsh Transform (DWT) by matrix vector multiplication which is easier to perform in 2D optical system where processing can be done parallely in 2D. The computation of DWT in such an optical computing architecture is much easier to perform and requires less processing time. A methodology is also proposed where a microprocessor is utilized to sequentially process matrixvector operations on digitized data. The result is stored in the memory for display and/or read out.
