Abstract

In this paper, a new high-resolution (XGA) SLM is implemented through modification of a commercial TFT-LCD beam projector and its optical modulation characteristics are analyzed as well. The optic module, projection lamp and cooling fans are removed from the beam projector and instead, the electric circuits to compensate their removal are manufactured and inserted into the beam projector, a new high-resolution SLM is finally implemented. Some experiments on the optical modulation characteristics of the implemented SLM have been carried out by using the Mach-Zehnder interferometer. These experimental results show a good optical linearity in amplitude and phase modulation and as a result, the implemented LC-SLM is suggested as a new low-cost, high-resolution input and filter devices for the optical information processing systems.
