Wide Dynamic Range Analog Signal Optical Communication System.

摘要

The patent application describes a system for transmitting low level analog signals wherein the analog signals are converted into frequency modulated light amplitudes which are transmitted by means of an inexpensive fiber optic bundle, and the transmitted modulated light is demodulated at the receiving end to obtain an exact replica of the input signals. The system enables one to maintain a large amplitude dynamic range using an inexpensive photo-transistor.
