Opis:: This paper deals with the phase shift development between two polarization modes in birefringent fiber, caused by body heat transfer of different temperatures. The aim is to analyze sensitivity and dynamic behaviors, which are significant when optical fiber is used as a sensor of temperature field disturbance. The analysis is based on the values measured during thermal exposure of a section of type PANDA birefringent optical fiber to heat emitted by an exposure body of chosen temperature, placed at a defined distance. The effect of heat transfer through conduction and convection is suppressed by shielding with plastic wraps. The analyzed results, the Stokes parameters and subsequent phase shift, are measured by the polarimeter. The paper follows up on previously published measurement results.

Opis:: This paper deals with the phase shift development in the polarization-maintaining fiber owing to different temperatures of an applied defined body, where both polarization axes are excited. A variation of the Stokes parameters induced by the phase shift is expressed by the Jones matrix and a depiction on the observable Poincaré sphere. The temperature response of polarization-maintaining fiber and the effects of heat transfer on the phase shift variation of polarization-maintaining fiber were described theoretically. The time dependence of the phase shift development and its direction of rotation on the observable Poincaré sphere was measured and presented graphically. In addition, different response measures for higher and lower temperatures compared with the ambient temperature were experimentally evaluated.
