Abstract

Injection is an economical method of producing plastic holographic optical elements (HOEs) in large or small quantities and of various types. A computer-analysis system is used to simulate and control the results of the manufacturing system. A computer program, based on coupled-wave theory, predicts and evaluates the diffraction efficiency of a hologram. The CAEMOLD computer simulation software assists in calculating and modifying the injection process. A fuzzy control model is used to obtain the proper operating parameters. These techniques can obtain uniform distribution and a high diffraction efficiency in the plastic HOE product from the results of the computer controller.
