Abstract

By emitting an encoded light signal into a fiber optic sensor the application of the AC/DC compensation technique can be extended to stabilize sensors in static measurement. The source coding is a process that light signal is modulated, and the sensor functions as a decoder to the corresponding encoded light signal. Modulation depth of the decoded light signal can be changed by the DC measurand. A phase-encoded light source is used to demonstrate this technique where the white light interferometer is employed as the decoding sensor.
