报道了一种用于测量光束色散和相移的新型马赫-曾德尔（M-Z）干涉仪。该干涉仪由两个相同的光束位移偏振器组成，使两束干涉光通过同一光学器件，大大提高了M-Z干涉仪的稳定性。详细介绍了利用该干涉仪测量色散和相位的基本方法，并通过具体实例说明了其实际应用。由于色散和相移的测量一直是光学领域的热点，因此M-Z干涉仪在光学领域，特别是量子光学和光信息处理领域有着重要的应用前景。
A novel Mach—Zehnder (M-Z) interferometer used to measure the dispersion and phase shift of a light beam is reported. The interferometer consists of two identical beam displacing polarizers, which makes two beams of interference light pass through the same optical device and greatly improves the stability of the M-Z interferometer. The basic method of dispersion and phase measuring through the present interferometer is introduced in detail, and the actual application is demonstrated by a specific example. Because the measuring of dispersion and phase shift is the heating point in the field of optics, it is obvious that the M-Z interferometer will have important applications in aspects of optics, especially quantum optics and optical information processing.
