Abstract

The performance of an improved Microchannel Spatial Light Modulator is discussed. In order to improve the spatial resolution, a very thin crystal (approx. 50μm thickness) is adopted and the device structure is refined. This new device has a spatial resolution of approx. 10 1p/mm at 50 % modulation. Also, the contrast ratio is improved. It is achieved by coating the surface for the charge storage of the crystal with a dielectric mirror and coating the opposite surface with an anti-reflection coating. Moreover both surfaces of the output glass window are coated with an anti-reflection coating. The improved contrast ratio is more than 3000:1.
