Paper Abstract

Re-entrant fiber optic gyro (Re-FOG), using a shorter Sagnac sensitive ring (SSR), makes parts of the two counter-propagandizing lights re-enter the ring before they interference with each other when they reach the photo-detector. Multiple-integrated-optic-chip (MIOC) is one of the most important components of a Re-FOG. In this paper, the principle of the Re-FOG is first reviewed. A method of measuring the half-wave voltage is presented. The thermal induced change of half-wave voltage was tested.
