METHODS AND APPARATUS FOR INTERFEROMETRIC INTERROGATION OF AN OPTICAL SENSOR
Last updated:
Abstract:
A high-speed interrogation system is provided for interferometric sensors, one example of which is an EFPI sensor, that operates based on spectral interference. The system uses a two mode operation that includes a lower speed, accurate absolute measurement mode and a higher speed, relative measurement mode. The system achieves greater overall measurement accuracy and speed than known sensor interrogation approaches.
