A new and innovative single-mode fiber interferometer is proposed for the wave-front test of the adaptive optics (AO) system. It is based on a modified Mach-Zehnder interferometer with the two arms replaced by optical fibers. It avoids the difficulty of fringe interpretation of the conventional Mach-Zehnder interferometer. As fibers are used, the whole instrument is compact, flexible, and suitable for the AO on-site test. Furthermore, as minimum optical components are used, the interferometer is free of calibration and has high measurement accuracy. The operation of the interferometer is also very simple, and wave front can be tested quickly. We discuss the working principle, experiment setup, fringe analysis, and its application for an existing AO system. The interferometer can also be used to test wave aberrations of a single lens or an optical system.
