Abstract
Digital transforms, such as Walsh or Haar transforms for example, are often used to improve the quality of the picture and obtain a better resolution. The mathematical computer procedure of the transform operation can, however, be lengthy and complicated. We suggest use of coded holography with a mask representing the Walsh or Haar transform as a reference beam. Details of the set up and the construction of the mask are discussed and the results are shown.
