Abstract :
At present, the most promising technique for demodulating frequency-modulated (FM) light is to convert the FM signal to an AM signal; the AM signal can then be demodulated by a microwave photo tube, photodiode, or other means. This paper deals with the discrimination process, i.e., the conversion of FM light to AM light. In particular, we describe several discriminators composed of birefringent crystals and polarizers.
