To resolve the light-intensity variation and the inherent non-linearity problems of reflective intensity modulated fiber optic displacement sensor

an embedded fiber optic displacement sensor is designed.A displacement sensor takes random distribution and concentric distribution fiber bundle as sensing unit

and an embedded AduC812 is used to accomplish signal sampling

linearized processing and outputting.The application of ADuC812 is analyzed.By introducing ADuC812

the measurement performance of fiber optic sensor is improved with the response sensitivity of 6 kV/m and the linear error less than ±1 %.It will find a greater application.
