Abstract
A spatial light modulator comprising an array-type liquid crystal panel, a polarization beam splitter, an oblique wave plate and a converging lens. The polarization beam splitter is orientated to direct a source light towards a reflective planar surface of the array-type liquid crystal panel. The oblique wave plate and converging lens are located between the polarization beam splitter and the array-type liquid crystal panel. The converging lens is configured to direct light from the reflective planar surface onto a facing surface of the polarization beam splitter.
