Paper Abstract

This paper puts forward a new large-aperture high-accuracy interferometer for flow visualization and optical shop testing. The interferometer uses a Twyman-Green interferometer as a beam splitter, and a grating as a detector. Using this interferometer to measure the flow fields in a shock tunnel and to test optical elements obtained some satisfactory results.
