摘要：

The temperature and strain response of fibre Bragg grating sensors in a cryogenic environment has been evaluated. The fibre Bragg grating temperature response was found to be nonlinear, decreasing to approximately zero for temperatures less than 100 K. The response to strain was found to be temperature independent.
