Pagination or Media Count:
Acoustical amplitude and frequency modulation techniques of a CW helium-neon laser beam are presented. tThe communication possibilities of this beam for both cases AM and FM are verified. Theories are discussed for the acoustooptical modulator and the p-i-n silicon photodetector. Designs of the elements of the systems and experimental results are presented. Operation of both systems is discussed. Author
