High resolvance interference spectrometry with a high factor of merit in the visible spectrum

Abstract

Thanks to the laser, high definition photographic plates, and an achromatic compensation phenomenon applicable to equal inclination fringes, the spectrometric method, based on an analysis of Fabry-Perot rings through an adapted grid, is now simple to use, as shown in this paper. Experimental results are given and compared with those obtained from the conventional Fabry-Perot spectrometer.
