Temperature sensing using optical fibers in harsh environments

Temperature is a major magnitude that needs to be measured in many different scenarios such as monitoring the temperature during manufacturing process, in aeronautical engine performance, or in all electrical aircraft batteries performance among others. Fiber optic temperature sensors have very interesting properties due to its potential to provide electromagnetic interference immunity, light weight, intrinsically safe nature, and depending on the technology high temperature range and remote operation. In this talk we will review our recent progress on intensity fiber-optic temperature sensing with different technologies and applications.
