ABSTRACT:
A novel control method and attendant apparatus for controlling other various methods/processes by utilizing a photoacoustic effect principle, whether or not the other various processes are with regard to solid or non-solid fluid media, but which other various processes use and require control of a primary excitation high energy beam and related beam-modulating and monitoring apparatus for establishing and detecting a photoacoustic effect. This method and apparatus require the use of appropriate beam generating and beam-generating power control means for controlling such an energy beam, the latter of which may be of the type including laser beams, microwave beams, x-rays and other electromagnetic wave beams, as well as ion, electron, particle, and molecular beams. Various beam modulating means may be used as well as various techniques for monitoring and detecting the photoacoustic effect, such techniques including different apparatus related to respectively different techniques, including a gas cell means, mirage generating means, piezoelectric detector means, infrared radiation detector means, and the reflective probe beam means.
