Abstract

Comparing with interfering of laser beam used in the position measurement, the method of white light interfere can be used in the measurement of absolute position. As the zone of white light interfering is very small, so the limitation of relative measurement by using laser can be avoid. The equipment for interfering measurement of multi white light beam with one referent white light under the law of white light interfering is presented in this paper. The original light in this equipment is divided into several parts, and each part is made as one incident source of one sensor. The optical fiber sensor modulated the light above in phase and then the output light will interfere with the reference light. As the range of white light interfere occurred is very small, so the optical path of multi white light beams can be measured within one step of scanning by the equipment described in this paper. The method given in this paper is one of the most proper methods for fusion measurement in distributed optical fiber sensor.
