Abstract:   (2016 Views)
In this paper, the optical fiber sensor based on the Fabry Perot interferometer has been proposed. High temperature sensitivity, easy construction, robust and small size are the advantages of this sensor. The main structure of this sensor is a PDMS cylinder and within this cylinder there is an air gap with an approximate length of 220 microns. The sensitivity of the air gap is equal to 15 nm / ° C.
 
Keywords: PDMS, fabry-perot interferometer, optical fiber sensor, temperature sensor
