A simple real-time interferometer system was developed for use in dynamic stall and other
unsteady flow research at compressible flow speeds. A conventioned schlieren system was
modified to operate as a point diffraction interferometer. The implementation of this
interferometer is discussed and results of trails with different point diffractors are
presented in this paper. The performance of the interferometer under various flow
conditions was investigated. Results are presented which show the effects of the interferometer parameters such as pinhole size and pinhole-plate optical density on the performance of
the system.
