Abstract

The use of optical bridge compensating structure in fiber optic sensor is studied thoroughly in this article. The stability of the compensating structure is essential to achieve good results. A fiber optic pressure sensor based on this compensating structure has been put into practical operation for oil storage measurement in tanks, and the long term stability of the sensor is better than 0.2 percent. This compensating technique has also been used in a LADAR fiber optic liquid level sensor system which combine discrete frequency IMCW LADAR and fiber optic sensor technique together, realized liquid level measurement effectively. Our studies proved that optical bridge compensating technique must be used with appropriate structure in different kinds of sensors and are very important to sure of the stability of fiber optic sensor.
