title: Implementation of general point transforms with diffractive optics.
abstract: All linear finite-dimensional transformations can be implemented with diffractive optics. Such transformations include general point transforms. A technique for the implementation of general point transforms is considered. This is used to implement two point transforms. The implementation of a 90°-rotation and a Hough transform is discussed. Fresnel diffraction patterns of these implementations are presented.
