Abstract

An optical fiber sensor for measuring the rotatory power of substances, which can be used to take the remote real-time detection based on optical activity, is presented in this paper. The range in which the optical activity can be measured is +/- 90 degree(s)S for this setup. Owing to the fact that optical zero point of 45 degree(s) is adjusted, the double optical paths, electric bridge equilibrium, and the compensation measured method are employed. The influence caused by instability of optical source and vibration of equipment can be eliminated, and the signal-to-noise ratio can be greatly enhanced.
