DEEP SPACE OPTICAL COMMUNICATIONS SYSTEMS STUDY

摘要

Since knowledge of both current and extrapolated component and systems capability is required in such a study to suitably define a program for advanced studies, research, and development, several areas of technology had to be surveyed and analyzed. In particular, laser, optical detector, and modulation systems technology had to be carefully explored and boundaries of performance described.nUtilization of the laser with its novel properties required that exten-sion of current communications knowledge be analyzed in terms of support-ing equipment. It was found, for example, that the operating frequency, power output capability, spectral purity, etc. required by the system, call for increased performance from optical detectors in regions of the spectrum where no such demand previously existed.
