Abstract
An optical space communications transmission and reception terminal includes: an optical transceiver to convert transmission data into a transmission optical signal modulated at a symbol rate synchronized with a transmission clock signal and output it, and generate received data from a reception optical signal; an intensity modulation unit to generate an intensity-modulated transmission optical signal; a transmission clock source to supply a transmission clock signal; a fiber coupling unit) to output the intensity-modulated transmission optical signal as collimated light and couple the input optical signal to an optical fiber; an optical fiber amplifier to amplify the optical signal coupled to the optical fiber; a tracking mirror to output the optical signal to the fiber coupling unit and output the transmission optical signal to space; and an angle sensor to output a clock signal extracted from the optical signal divided by a beam splitter to the optical transceiver.
