APPARATUS, METHOD AND COMPUTER PROGRAM PRODUCT FOR INTERROGATING AN OPTICAL SENSING ELEMENT |
摘要 |
A method for determining deflection of an optical sensor having an optical cavity includes: providing an optical signal including a train of time spaced light pulses, each light pulse including a known set of wavelengths; splitting the optical signal and providing a portion of the optical signal to a reference path; detecting light pulses in the portion of the optical signal; using a remaining portion of the optical signal and interrogating the sensor; receiving a reflected optical signal from the sensor; detecting light pulses in the reflected optical signal; and analyzing the portion of the optical signal and the reflected optical signal to determine the deflection. Corresponding apparatus and computer program products are provided.
