由于双镜激光干涉仪比马赫-陈干涉仪有许多优点,本文应用双镜干涉仪测量了空气变形丝喷咀的超音速气流的流场,得到了满意的结果。
Because of the advantages of the dual-mirror laser interferometer compared to the Mach-Chen interferometer, the flow field of the supersonic airflow in the air-jet nozzle is measured by the double-mirror interferometer. The satisfactory results are obtained.
