Abstract
A miniaturized fiber Bragg grating (FBG) interrogation system may comprise a light source, a FBG sensor, and a photodetector. The FBG sensor may be configured to receive an optical signal from the light source, interact with a transmitted spectrum of the light source over a discriminating spectral domain, and generate a reflected optical signal representative of a change in a physical signal sensed by the FBG sensor. Additionally, the system may include a power management unit configured to reduce power consumption in order to prolong the lifespan of the system.
