  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.
