Abstract

Based on mutual compensation characteristic of the photoelastic and electrooptic birefringence or phase retardation in crystal or glass, an optical stress sensor is designed in principle by use of single bulk crystal or glass. Particularly, the crystal is used as both stress sensing element and electrooptic phase modulator. The configuration of conventional optical stress sensor is simplified, and closed-loop stress measurement is also possible.
