In this work, we demonstrated an ultrasensitive parallel double Fabry-Perot interferometers (FPIs) sensor based on Vernier effect and Type II fiber Bragg grating (FBG) for simultaneous measurement of temperature and strain in the temperature range of 26 C-1000 C. Two FPIs are manufactured from hollo...
