Abstract :
In this paper an interesting high-precision optical displacement sensor based on fiber optics and intensity modulation is presented. The proposed sensor has below nm precision and so excellent for high precision measurement and instrumentation systems design and implementation. The proposed method is so easy for implementation and based on diffractive optics. With variation of the barrier the reflected intensity is varied and this is a measure for distance.
