A system approach in the theory of optical spectral measurements

Аннотация

This paper develops some elements of an alternative theory of optical range spectral devices in which the spectral decomposition is performed by the linear processing of the analyzed optical radiation. Within the system approach, the spectral devices that include the diffractionand resonator-type ones are divided into two subsystems performing the linear and nonlinear transformations of the optical radiation, respectively. The investigations involve methods from the system approach, linear system theory, wave optics, and radio optics.
