The hardware and software design of the dynamic radiation scanning thermometer was presented in this paper. The hardware part contained optical part and circuit part. The optical part was composed of optical scanning mirror, laser, lens and aperture stop. And the circuit included pre-amplifier circuit and data processing circuit. In the circuit part, the pre-amplifier circuit was composed of pre-amplifier AD820, inverting amplifier OP07 and relay components, while the data processing circuit was composed of STC12C5A16S2 microcontroller, MAX232 and 12864k12 LCD display. Besides, matrix keyboard was used which can set emissivity, scanning frequency and reset. AC/DC module was used as the power module. The thermometer was designed with high accuracy, fast response, easy testing and carrying and many other advantages. It can also be used in some serious conditions, such as high-risk, high-radiation, high corrosion. Thus, the market application prospect is very broad.
