| Abstract: | In this paper, a temperature sensor employing optical he- terodyne detection technique is introduced which uses a steady frequency longitudinal Zeeman laser as the optical source, using the polarization pre- served optical fiber as the sensing element which has a high degree of intrinsic birefringence. Theoretical analysis is made on operation prin- ciple for experiment system and the main performance parameters are also given. |
