The Design of Optical Fiber Displacement Sensor System

摘要

Introduced Fiber Optic Displacement measurement principle, Through setting the reference channel, useing of modulation and demodulation technology the system eliminates interference caused by changes in non-measured light intensity effectively. After data time-sharing acquisition, the SCM system will complete the function such as the identification and the difference between the measured signal computing, data processing, more limited display and alarm . The system's measurement range 0 ~ 1.300mm, accuracy up to 1 ‰.
