abstract

A fiber optic intensity based sensor for remote inclination measurement has been developed based on light beam displacement caused by a free hanging deflector glass plate as it changes its angular position relative to the body of the sensor. Light intensity drift compensation is achieved through the comparison of two output signals obtained from the two spaced measuring channels integrated in the sensing element. The specifications of the sensor are as follows: threshold sensitivity - O,01°, dynamic range - 25 dB, measuring angle range - ±4°. As a result of sensor performance equalization its output signal variation corresponding to 30% input light intensity decrease does not exceed ±4%.
