A portable infrared device for rapid detection of thermal imaging device (MR) MRTD is introduced. It is composed of infrared optical system, target, blackbody of surface source, temperature control device and display device. The temperature difference source composed of the target and the surface-sourced blackbody is imaged to infinity by the infrared optical system to simulate the infinity target and is supplied to the thermal imaging device for receiving. The optical system uses the telephoto objective lens structure to realize the portable requirement. The temperature of the target and the surface source black body is controlled by a temperature controller, and the data acquisition, processing and display are performed by the Z80 single-chip microcomputer, and the temperature control process of the certain method ensures the target Accuracy of the temperature difference between blackfaces. Small size, light weight, easy to operate, reliable performance, the technical indicators have reached or exceeded the design requirements.
