Interference contrast function in unbalanced fibre optic Michelin's interferometer

摘要

This paper presents influence of change spectral parameters of radiation source on course of interference contrast function of unbalanced Michelson's interferometer. This function is according to difference change of arms length L. The analysis was presented for changes of wavelengths λ， half width of spectral line △λ and distance between spectral main line and spectral side line β in the radiation spectrum of semiconductor laser.
