RESEARCH OF TECHNIQUES FOR LIGHT MODULATION DETECTION. PART I. AMPLITUDE DEMODULATORS.
Abstract
The results of a one-year applied research program on the demodulation of amplitude-modulated (AM) light are presented. Sufficient information is provided for the detailed understanding, design, and use of traveling-wave microwave phototubes (TWPs), the most promising detector for broadband-modulated light. The report includes: (1) the idealized analysis which first pointed out the more important TWP design considerations and operating characteristics; (2) a more complete computeraided analysis which gives detailed information on the effects of the various beam-circuit parameters and operating conditions; and (3) an analysis of the electron gun region, with emphasis on velocity spread and current density effects. The results of a detailed experimental analysis of the TWP are presented, providing both verification of the more complete theoretical treatment and information on generally-useful photodetector test techniques. Experimental data are given on several other types of photodetectors. A discussion of the design and construction of TWPs with S-1 photocathodes contains material of practical importance to TWP builders.
