Abstract

Computer generated optical fringe patterns provide valuable information to the experimentalist. They can be used to compare the results of an experiment with a theoretical solution, aid in the planning of experiments or used to perform conceptual experiments. This paper discusses several straightforward fringe plotting algorithms that have been developed by the authors for the purpose of generating fringe patterns on a computer. The emphasis of the paper is on the generation of fringe patterns using high-speed line printers or dot matrix printers which allow the formation of pseudo-gray scale images. Examples of particular interest to speckle researchers, including displacement patterns and Young's fringes, are presented to illustrate the algorithms developed.
