Abstract
Considered in this report is the principle of a novel measurement technique laser refractography used to diagnose near wall and boundary layers developing in liquids as a result of temperature or concentration gradients occurring therein. This technique is based on the probing of the transparent liquid of interest with a structured optical radiation produced by means of diffraction optical elements and the digital recording and processing of the refraction patterns obtained.
