Multi-alternative Automatic Control Based on Spectral Measurements by Diffraction Devices in the Optical Range

Abstract

This paper considers the possibility of multi-alternative automatic control of physical and physicochemical processes accompanied by optical emissions. The control is supposed by means of formation of output vectors based on spectroscopic measurements by diffraction spectral devices, which are performed by prism and grating diffraction spectral devices. The result of the spectroscopic measurements is an output vector and its formation is based on a new, nontraditional approach to describe the process of measuring the energy spectrum of the measurement signal by diffractive optical spectral devices, which are considered as consisting of two parts - linear and nonlinear. By reading the energy spectrum using a CCD line, output vectors can be formed from the received photocurrents of each pixel and thus enable multi-alternative automatic control based on spectroscopic measurements to be realised.
