A Computerized Laser Refraction Method of Examining Optically Inhomogeneous Flows

  • Published:
Measurement Techniques Aims and scope

Abstract

The theory is given for a new computerized laser refraction method for displaying and examining nonstationary processes in flows. The method is based on the computerized processing of refraction patterns produced by laser beams passing through the optically inhomogeneous flow, in which there are nonstationary gradients in the parameters. Examples are given of displaying thermal processes in natural convection in water.
