【Abstract】 This paper describes the designing principle, structure, performance test and analysis of GaAs temperature sensor with a single-chip computer and optic fibre which is used to measure the cancer temperature in clinic of microwave or radio-frequency hyperthermia. The sensor is in a single-end output type, and adopts an excellent signal process project of double wavelength, single way and ratio output in design, thus making the sensor has high stability and good practicality.更多还原
