Ecological Systems and Devices Annotation << Back Research of dynamics of signal detection of the laser device at control of pathogenic microorganisms by the SBS-method Tomilin V.I. Mogilnaya T.Yu. Kononenko A.B. Now is particularly acute a question of automatic monitoring of parameters of drinking water directly in a stream. For the solution of an objective possibly use of resonance laser control methods. Application of IR-spectroscopy becomes complicated with need of use of high energy for possibility of allocation from total number of hindrances of an informative signal, it doesn’t allow to use optical fiber, and it does necessary to transfer radiation by air that leads to increased errors. The most perspective method of the solution is application the SBS-method (method of stimulated Brillouin scattering). The experiment technique is presented in this article, the description of the laboratory device, the algorithm of detection of features of time of a delay and attenuation a component of an optical signal is mainly stated, results and the analysis of a collected database are presented. Keywords: Brillouin scattering; SBS-spectroscopy; resonance method of control. Contacts: E-mail: moguilnaya@mail.ru Pp. 09-13.
