Abstract
The optimization and realization of the relief structure for binary diffractive elements is implemented through a computer program which has been named DIFFOPTRAN. The program's input can consist of the required phase profile generated by some external means, such as CODEV, or the user can select analytical forms for the various input parameters, e.g. planar or curved surfaces, incident beam profile, or phase functions describing gratings or other optical elements. DIFFOPTRAN is capable of propagating gaussian or supergaussian beams through the optical element in its original description as conventional refractive elements, or it can perform conversion of the input element into a binary diffractive element and then propagate a beam through it. The propagation can be done as a function of various parameters. The efficiency, beam sizes and centroid postions are computed in the observation plane.
