Abstract
A new highly accurate temperature sensor for biomedical applications is proposed in this invention. This sensor including two fiber Bragg gratings with different thermal coefficients can accurately measure temperature with little laser frequency stabilization. This invention improves the measurement resolution and accuracy. Such a sensor can be used to calibrate the other fiber biomedical sensors when those fiber sensors are packaged together.
