| Abstract: | The temperature characteristics of linear birefringence and its effect upon the output of a bulk glass current sensor is theoretically analyzed and simulated. The results show that when temperature field distributes evenly, the linear birefringence induced by the mutual pressure between sensing head and surrounding material of the package is the main factor, the sensitivity of the system could be varied more than 1% during changes of temperature within the range of −40–40 °C. These results might be useful to those studying optical glass current sensing techniques. |
