A rapid light path adjustment method of a white light cutting interferometer, and the like mainly utilizes an adjustable chatter laser as a light source to change the motion speed of interference fringes generated by the interferometer and observe the motion situations of the interference fringes of an observation screen of the white light cutting interferometer through adjusting the wavelength width of a laser pulse and adjusting a movable light path of the white light cutting interferometer, thereby the rapid adjustment of the light paths of the interferometer is realized. The method has the advantages of simplicity, convenience, rapidness and gradually controllable accuracy.
