DTIC AD0410264: RESEARCH ON TECHNIQUES FOR LIGHT

More Book Details

Description of the Book:

An applied research program conducted by the Sylvania Microwave Device Division to establish techniques for light modulation detection is covered, and it concludes a one year program on amplitude modulation (AM) detectors. Sufficient information is provided for the detailed under standing, design and use of traveling-wave microwave phototubes (TWP’s). The major topics are: (1) an analysis of the dependence of power output on the large spread in initial velocities from photoelectric cathodes; (2) analysis of theversion of current modulation to velocity modula tion in the gun region of a TWP; (3) detailed calculations of equivalent conductance, Geq, which expresses the way in which velocity modulation is converted to circuit power; (4) compre hensive measurements on TWP’s and comparison with detailed theory; (5) suggestion and utilization of a novel technique for measuring Req; and (6) a summary of research contributions on the AM demodulator program
