A portable testing system for high-temperature with infrared laser spectral detection principle is introduced.Applied new thermometry which combined spectral absorption with high-temperature radiation in temperature testing

the infrared sensor for high-temperature detection is designed.The ARM hardware platform centralized on S3C44B0 is developed.It consists of A/D conversion module

LED display module and serial port communication module.Compared with the traditional sensors

the infrared sensor for high-temperature detection is characterized by rapid respond speed and high accuracy.With the ARM embedded processor

this system has advantages of good real-time performance

offline operation and portability.It has the broad application prospect.
