A new Method of Wavelength Measurement Using Michaelson Interferometer

Some factors affected the experimental process in experiment of wavelength measurement using Michaelson Interferometer,such as the optical route adjustment and many measuring data errors.According to the theory of wavelength measurement using Michaelson Interferometer,we put forward a new measuring method that silicon photovoltaic cells as photoelectric sensors and cooperating with multimeter to realize quantitative measurement.This method not only markedly improve the accuracy of measurement and efficiency,but also has the performances of steady and low-cost.
