Abstract
The method of digital processing of laser radiation interference pattern with the digital microscope and original two-beam interferometer with the phase Bragg grating as the amplitude beam splitter for a quantitative determination of the spatial and temporary coherence module of radiation is described. The digital processing of the interference pattern images was carried out with known software algorithms. Principles and functionality of a measurement procedures are demonstrated on measuring of the radiation coherence of several gas, solid-state and diode lasers.
