Description	A new sapphire fiber high temperature sensor sputtered the ceramics film is described. The system includes blackbody sapphire fiber sensor, taper fiber, transmission optical fiber, narrow bandpass filter, integrated photoamplifier and data acquisition device. The working principle, block diagram, static calibration dynamics testing and excremental result are given. The adoption of sapphire fiber makes the measured high temperature up to 2000. The static calibration is performed by comparing the outputs between the calibrated Tungstenrhenium thermocouple and the sapphire fiber sensor, both placed in a stability high temperature field. The dynamics character is done by focusing a CO2 laser with high peak power into the sensor. Dynamics respondent curve shows that its respondent time is less than 20 ms, which is suitable for measuring the transient high temperature such as the burning and exploration of powders as well as the firing of engine. Finally, high temperature during the launch of certain rocket is present firstly.
