Abstract
A system and a method for controlling the scale factor of a fiber optic sensor are disclosed. The scale factor may be maintained at a constant level by controlling the power level of the light source based on the amplitude of a modulation superimposed on the modulator drive signal. Alternatively, scale factor may be maintained at a constant level by setting the detected signal at twice the modulator drive frequency to zero.
