Paper Abstract

The problem of communication of the spectral characteristics of sources the optical radiations with the assay values of their spectra optical spectral device (SD) base on the acoustooptic tunable filters (AOTF) is decided. For three kinds of a control signal basic performances of teh optical SD based on AOTF are determined: a spectrum spread function a transfer function and a pulse response. It is contacted between them. The procedure of transformation of SD random signals of optical sources is described. In the capactiy of control signals the following are observed: a simple harmonic motion, oscillation iwth linear variation of an instantaneous frequency and oscillation with step variation of an instantaneous frequency. A mathematical modelling process of spectral measurements by an optical part of SD is made and also questions postdetection processing of the spectrometric information are probed. Recommendations of mode selection of SD are formulated.
