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 as a spatial light modulator(SLM) is also analyzed. That is, the optics module, projection lamp and fans are removed from a commercial beam projector and instead, some electric circuits to compensate their removal are manufactured and then, by inserting them into the beam projector, a new XGA-SLM is finally implemented. From some characteristic experimental results of the implemented high resolution TFT-LCD SLM, the proposed TFT-SLM is found to have an good optical linearity in amplitude and phase modulation characteristics as a function of the input gray levels. Especially, through implementation of the suggested TFT-LCD panel, the implemented SLM is proposed as a new relatively low-cost and high resolution SLM for optical information processing.
