Extended dynamic range one dimensional spatial light modulator |
摘要 |
An optical information system which uses a liquid crystal television (LCTV) as a one dimensional spatial light modulator (SLM) is presented. An optical carrier wave is generated by polarizing and collimating the output of a laser. The liquid crystal television modulates the optical carrier wave with a digital modulating signal to output thereby a modulated optical signal: An array of photodetectors electroptically connects the modulated optical signal into a modulated electrical signal which is displayed on an oscilloscope. The use of an LCTV as a one dimensional SLM yields higher numerical accuracy and extended dynamic range than two dimensional SLM applications of the same equipment.
