Electronic Feedback System For Stabilization Of Fiber Interferometer
When a constant laser light passes through the fiber interferometer we expect the constant output intensity but
due to temperature fluctuations and mechanical vibrations the phase of the light passing in one of the arms changes with
respect to another and we get the drift in the output voltage. Conventionally lock-in amplifiers are used but they are expensive
and complex. Hence, we have designed an electronic feedback system to compensate the drift in the output voltage.
