Research on fiber-optic intensity-modulation acceleration sensors
A transmissive intensity-modulation fibe-optic acceleration sensor is designed.A pigtailed collimator with a built-in Gradient-Index(GRIN) lens is directly used as a sensitive mass and two collimators are adopted for reception.The optical coupling efficiency of the light path is improved by addition and subtraction and ratio operation and the effects from light source disturbance and microbending loss are effectively compensated and the simulated computations and initial experimental data are given
which indicate that this acceleration sensor has good linearity
