Abstract
The principle of this sensor function is based on polarization maintaining fiber (PMF) sensitivity 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 indicator. In the case described below, attention was devoted to temperature field disturbance on a 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.
