【Abstract】 The working principle of a novel optical fiber temperature sensor with metal coating is analyzed. The results of experiment show that the characteristics of this sensor depend on the structure parameters of etched fiber sections and the type of metal coating material. The response under temperature change is linear, repeatable and no measurable hysteresis. The sensor has higher temperature response sensitivity.更多还原
