【Abstract】 A novel optic fibre teperature sensing scheme is presented firstly, which employs the principie,that the angles of heat double metal temperature control cells can change when temperature is changed.to modulate the intensity received by receiving optic fiber in this system.Satisfying linear results are obtained in a range of 0～100℃.Sensors with this scheme will have features such as simple configuration,reliable performance,lower cost, especially suitable for those circumstances easy to burn or to explode, therefore it is expected that the sensors using this scheme will have wide applicability.更多还原
