Application of Laser Gyro in Spectroscopy

摘要

The report is devoted to implementation of a laser gyro in optical spectral devices. The spectral device design principle on the basis of laser gyro is reviewed. The technical characteristics of the GS1L goniometer-spectrometer, main measurement circuits and equations for calculation of refractive indices of optical glass are described. The experimental measurement results, obtained on the international program of refractive indices measurement comparisons and organized by initiative of Physikalish-Technische Bundesanstalt (PTB, Braunschweig, Germany) are presented.
