Abstract
The intrinsic Fiber Fabry-Perot (FFP) sensor is being considered for strain sensing in smart structure applications. The current art of FFP sensor fabrication as published in the literature is reviewed. A pseudo-heterodyne demodulation technique is presented and performance of the system detailed. The issue of thermally-induced apparent strain as it relates to fiber-optic strain sensors will also be introduced.Keywords
