Infrared thermal imaging cameras in the medium and long wavelength bands play an important role in the national defense and security departments. For thermal imaging camera manufacturers, maintenance units, scientific research institutes and end users, the testing of thermal imaging cameras is important. significance.
Provides four test systems to meet different thermal imaging camera test requirements:
-DT system (full-scale long-distance reconnaissance/scientific-level thermal imaging camera in laboratory environment)
The DT system is the most mainstream test system that supports the measurement of all important functional parameters of the infrared camera, including MRTD.
-SIM system (simplified measurement of laboratory environment and long-distance reconnaissance / scientific research-level thermal imaging camera)
The SIM system is a simplified testing system for infrared thermal imaging cameras, mainly based on resolution and focus testing.
-LAFT system (measuring long-distance reconnaissance thermal imaging camera under field conditions)
The LAFT system is a mobile testing system designed to measure long-distance reconnaissance thermal imaging cameras under field conditions.
-SAFT system (measuring short focal length thermal imaging camera)
The SAFT system is a miniaturized testing system designed to test infrared thermal imaging cameras with short focal lengths.

DT test system | Principle of Test System |
The DT test system is a high-end equipment specially optimized for comprehensive measurement of infrared thermal imaging systems under conditions such as laboratories or armory. By adding the option DT system, it is possible to comprehensively measure the performance parameters of TV (TV) and low-light-level TV (LLLTV) cameras.
The DT measurement system is a projection system that can transform a series of different targets. It projects the target image into the field of view of the thermal imager under test, and the thermal imager will generate a target image. By evaluating the quality of the target image produced by the thermal imager, the important performance parameters of the thermal imager under test can be obtained. . Different targets are used to evaluate different parameters. The different performance parameters of thermal imaging cameras are usually given by TAS software.
The DT system has a modular structure and can be optimized for different thermal imaging cameras; from short-distance thermal imaging cameras to long-focus reconnaissance thermal imaging cameras.
