Abstract: | Presented in this work is a new class of optical fiber temperature sensor, of which the heat-expansion thin film is coated
on the etched fiber. It uses the method that combine thermal carving technique with chemical etching. The sensitivity of the
sensor is increased and the shape size is decreased. This sensor possesses the linear temperature response and the good repeatability.
These sensors can be used to measure finely the temperature which is lower than 200°c. |
