Abstract

The article deals with a way of the influence minimization of the speckle modulation in the trigger type optical

probes on the output. The issue of discrete data acquisition is analyzed. Correlation function measurements of

the output signal envelope at several arbitrary points on the surface of the object are done. Obtained results are of

great practical importance for the trigger type optical probe.

Keywords: interference devices, optical probe, coherently limited radiation sources, speckles, correlation function, reference mirror.
