Abstract. Traditionally, the optics experiment of tradition takes the lead of the authenticating experiment and goes short of interesting and activity, meanwhile it is very unfavorable to the expansion of students' creative ability. In this paper, applications of Michelson interferometer in laser wavelength measurement and surface roughness measurement are introduced to extend basic experiments for Michelson interferometer. The wavelength and properties of two kinds of lasers are obtained; and the variation of the interference pattern with the flatness of metal surface is shown as well.

“…A moving mirror in the reference arm was used as the optical delay line to track the additional optical path length through the sample. In addition, a dispersive Michelson interferometer combined with a Fabry-Pérot resonator [18] was proposed to retrieve the refractive index dispersion from a single interferogram, named fringes of equal chromatic order. However, the system is complicated and a priori knowledge of the thickness of the sample is required.…”

An angle-resolved spectral Fabry–Pérot interferometer is reported for fast and accurate measurement of the refractive index dispersion of optical materials with parallel plate shape. The light sheet from the wavelength tunable laser is incident on the parallel plate with converging angles. The transmitted interference light for each angle is dispersed and captured by a 2D sensor, in which the rows and the columns are used to simultaneously record the intensities as a function of wavelength and incident angle, respectively. The interferogram, named angle-resolved spectral intensity distribution, is analyzed by fitting the phase information instead of finding the fringe peak locations that present periodic ambiguity. The refractive index dispersion and the physical thickness can be then retrieved from a single-shot interferogram within 18 s. Experimental results of an optical substrate standard indicate that the accuracy of the refractive index dispersion is less than 2.5 × 10−5 and the relative uncertainty of the thickness is 6 × 10−5 mm (3σ) due to the high stability and the single-shot measurement of the proposed system.
