| Abstract: | This paper presents the principle of a new large-aperture high-accuracy lateral shearing interferometer. The interferometer uses a Twyman-Green interferometer as a splitter, a grating as a detective element, real-timeMoire fringe method to eliminate the system errors. Its sensitivity can be easilyadjusted. It is applicable for the quantitative test of real flow field. The resultsobtained in the supersonic wind tunnel by the interferometer are given in thepaper. |
