A very simple method for visualization of phase objects is presented. The method is based on an incoherent pattern imaged by a CCD camera, with the fluid under test placed between the pattern and the camera. Two different exposures are taken. The first obtained with the fluid at rest, and the second with the fluid in operative conditions. By a quasi-real time processing of the two images, we obtain a visualization of the phase object under test.

Abstract

A very simple method for visualization of phase objects is presented. The method is based on an incoherent pattern imaged by a CCD camera, with the fluid under test placed between the pattern and the camera. Two different exposures are taken. The first obtained with the fluid at rest, and the second with the fluid in operative conditions. By a quasi-real time processing of the two images, we obtain a visualization of the phase object under test.
