Paper Abstract

This paper presents a digital holographic interferometer based on polarization holography. The setup was developed to analyze high density gradient flows. The set-up is less sensitive than a classical Michelson configuration since the test section is crossed only one time. Furthermore, the shadow effect limiting the other techniques is widely reduced. By using an astigmatic configuration, spatial carrier frequencies can be adjusted, so that a single shot and real time capability is obtained. Experimental results for a small supersonic jet when the injection pressure varies demonstrate the proposed approach.
