14.4 Drawbacks of Optical Interferometry
Despite the many benets of using interferometry, there are also drawbacks associated
with employing optical interferometers as sensors. ese tend to be related to the inherent
sensitivity of the whole interferometer to the surrounding environment, cross-sensitivity
to parameters other than that of interest, and what appear to be more complicated inter-
rogation system requirements when compared to other optical and nonoptical sensors.
