A Low-Cost Submicrolinear Incremental Encoder Based on 3[Formula Omitted]3 Fiber-Optic Directional Coupler

A high-precision displacement sensor has been developed for short-distance measurement with the interferometric method. This sensor uses a 3 3 fiber-optic directional coupler and a high-coherence laser source with 1550-nm wavelength to produce two interference patterns. A Lissajous figure is generat...
