ABSTRACT

Conventional interferometric measurements of weak phase objects run into serious accuracy problems due to low sensitivity and/or optical aberrations.This paper describes an optical method, based on the dual hologram technique, with enhanced sensitivity and with compensating for the optical aberrations. It provides a reliable acquisition of the phase information from wide range of weak phase objects including high speed flow fields.The method was demonstrated by mapping the density field of a small size axisymmetric supersonic jet as a representative weak phase object.
