Abstract:The sapphire fiber blackbody cavity transient high temperature sensor is described based on contact and
contactless measuring system consists of sapphire fiber sensor ,narrow bandpass filter , photodetector
,signal processing module,MSP430, data storage and software ,and analyzes blank-body cavity production and weak
photoelectricit signal detection. The control ability of the MSP430 is used to realize intelligentized and USB bus is used
municate puter .The experimental results show that the blackbody cavity has stable performance at a
high temperature and meet the harsh environment. The system has these merits such as simple hardware ,smaller size
and lower power consumption ,so it as value of spread and application.
