High sensitivity temperature and pressure sensor based on cascaded Fabry-Perot and Sagnac interferometers

Instrumentation Science & Technology, 2021
A sensor was proposed and experimentally demonstrated to improve temperature and pressure sensitivity by the Vernier effect. The sensor is composed of a cascaded Fabry-Perot interferometer (FPI) and a Sagnac interferometer (SI), which has almost the same

Thermal Drift of Optics in Separated-Beam Heterodyne Interferometers

IEEE Transactions on Instrumentation and Measurement, 2018
Designs of next-generation interferometers tend to place most of their emphasis on periodic nonlinearities rather than on thermal drift of the optics, which can contribute more than the well-known periodic errors to the overall error.
