Abstract

A novel high accuracy form error optical measurement system based on reflective intensity modulation optical fiber sensor is presented. Combing the optical fiber sensor technology and optical fiber communication technology, the system is developed by using optical switch to realize the Time Division Multiplex (TMD) of optical fiber sensing array, improve the system efficiency, reduce cost and suppress errors caused by the movement of optical fiber. SNR (signal noise ratio) and accuracy of the system are enhanced through lock-in amplifier. The intensity fluctuation of the reference light is adopted to correct the effects of the power variation of light source and so as to improve stability of the system. The experiment results show that the resolution of the system is up to 0.1μm and repeatability is about 0.5%. The architecture of the system is very simple that it can be used in multiple form error measurement of mechanical parts of different shapes by changing the number and layout of the optical fiber sensor array flexibly.
