New kind of spectral processing of optical signals - the analysis of sample spectra is considered. These spectra are variable in time and introduced into the theory of spectral optical measurements for the first time. Spectral devices calculating sample spectra in optical range are considered as linear systems. Spectrum spread function of spectral device that performs the analysis of a sample of the spectrum is introduced as a reaction to the function. It is a linear integral operator kernel which establishes spectral device input-output ratio. Complex sample spectrum is obtained by using a dispersing system which is considered as optical four-pole network, a comprehensive description of which is the transfer function.
