LIQUID CRYSTAL OPTICAL VALVE AND MANUFACTURE THEREOF |
摘要 |
A laser addressed reflective mode liquid crystal light valve includes an anti-reflective coating of only a single layer of cermet which is vacuum deposited in a partial pressure of oxygen to produce a combination of chrome and chromium oxide, the single layer anti-reflection coating both absorbing light at a wavelength corresponding to a laser beam wavelength and reflecting all other wavelengths with a higher reflectance. Some advantages are that fabrication is made easier by the elimination of multiple layers in the anti-reflection coating while laser beam absorption is enhanced by the single layer anti-reflection coating without causing a corresponding decrease in image resolution. |
