发明名称 Optical digital memory system
摘要 An optical memory having a light valve for each memory bit. Each bit is programmed in a WRITE mode to pass or inhibit optical energy emitted from a local source of illumination and thus store a binary value of "1" or "0". A short length of optical fiber guides light from the light valve in a READ mode to the core of a transmission fiber which acts as a series transmission line for an optical pulse sequence when each of a plurality of the light valves is illuminated by a respective optical source, e.g., a light emitting diode. An optical energy absorbing termination is located at one end of the series transmission fiber while an optical amplifier device is located at the opposite or output end and, where necessary in between, with the amplified pulse sequence from the transmission fiber being thereafter coupled to one or more individual optical receiver and transducer units which generate respective corresponding electrical utilization signals.
