NASA Technology Utilization Report (SP-5005) on the retrometer, a new system of voice communications transmitted an a beam of light, was published. Invented at NASA Langley Research Center by Numa E. Thomas, the retrometer differed from previous light beam-communications systems in that the originating station required no power other than the human voice. The T-U Report described the system, gave instructions for building experimental retrometers, and suggested many possible applications of the system. (NASA T-U Rpt. SP-5005; NASA Release 64-82)
