摘要：
The principle of a new large-aperture high-accuracy interferometer for flow visualization is presented. The interferometer uses a Twyman-Green interferometer as a beam-splitter, a grating as a detector, and a real-time moire fringe method to eliminate systematic errors. The interferometer has been used to measure the flow fields in a shock tunnel and obtained satisfactory results.
