Positioning Method for Optic Fiber Interferometer of Absolute Distance Measurement
A new optic fiber interferometer is proposed for measuring the absolute distance. It consisted of a positioning interferometer and a measuring interferometer, and used the stardard length optic fiber to enlarge the measuring range of the system. The method and the accuracy of the optic path positioning of the system are discussed in detail. Theoretical analysis and experimental results show that the positioning repeatability error is ±1 μm.
