The Analysis of Fiber Sensor of Temperature Field Disturbance by Human Body Part Access
2015
The principle of this sensor function is based on polarization maintaining fiber (PMF) sensi- tivity during excitation of both two polarization modes. This excitation is caused by temperature change, when absorbing thermal radiation. This mechanism is used for detection of temperature field disturbance as an in- dicator. In the case described below, attention was de- voted to temperature field disturbance on the part of the human body. Thus, this sensor system could be used for protection of some entity. The aim of this study was to determine the sensitivity of PMF to radiating heat, the space configuration and time response.
