The parallel spectrum analyzer of optical signals is presented. This device is one of spectral devices which receive spectroscopic information in an optical range. The method of receiving spectroscopic information based on the resonance phenomenon is described. The novelty of the method lies in implementing the spectral decomposition by the principle of the narrow-band optical filtration in n parallel channels of the spectrum analyzer. Furthermore, this device can make parallel analysis of spectrum of optical radiations which are in places of difficult access, for instance, in unfavorable conditions of high humidity, high temperature and toxic contamination. The result is achieved due to specific structure of the analyzer which contains n channels of spectrum analyzer and the group of optical fibers which transmits analyzed optical radiation on the given distance.
