An Optical Affine Transform Based on MEMS Optical Cross-Connect

Abstract

The two-dimensional optical affine transform is studied in this paper. Conventional optical affine transform is implemented by dove prisms, mirrors, and zoom lens,with the shortage of experimental adjustment difficulties, low accuracy, poor flexibility and stability. A method for optical affine transform based on optical fiber bundle and MEMS (Micro-Electromechanical Systems) optical cross-connect is proposed. An arbitrary optical affine transform is realized by making use of the switch property of MEMS combined with optical fiber bundle. The shortcomings of traditional methods can be overcome effectively by this way. The optical affine transform can solve the bottle-neck problem of speed in realizing image iterated function systems. Comparison of optical experiment results and simulation results proves the superiority of this method.
