Example Embodiment

[0031] This example Figure 1-2 As shown, it includes an infrared main body 1, a base 2 and a fixing clamp 3 for fixing the infrared thermal imager. The infrared main body 1 is connected to the base 2 through a support rod 4, and the lower part of the base 2 is provided with four leveling threaded feet 5. The fixing clamp 3 can clamp the infrared thermal imager, adjust its up and down position, and adjust its rotation angle, so that the infrared thermal imager is aligned with the infrared lens 6 in the infrared main body 1.

[0032] The infrared body 1 (see Figure 3, Figure 4 ) Is mainly composed of an infrared lens 6, a hollow metal target 7, a temperature control sheet 8, a temperature sensor 9 and a housing assembly 10. The housing assembly 10 is a heat-insulating metal sleeve. The temperature control fin 8 is a semiconductor refrigeration fin, which is controlled by the temperature controller 11. The semiconductor refrigeration fin is placed on the surface of the heat sink 12,...

Abstract

The invention relates to a device for simply and conveniently detecting performance parameters of an infrared imaging system, which comprises an infrared lens, a hollowed metal target, a temperature control chip, a temperature sensor and a shell, and is characterized in that the shell is a heat-insulated metal sleeve; the temperature control chip is positioned at one end of the heat-insulated metal sleeve, and the infrared lens is positioned at the other end of the heat-insulated metal sleeve; the hollowed metal target is arranged near the focal surface of the infrared lens in the heat-insulated metal sleeve through a target supporting device; the temperature sensor is arranged on the hollowed metal target; and a hollowed part of the hollowed metal target is positioned on a light path between the temperature control chip and the infrared lens. The device utilizes the imaging principle to simulate a distant target, meets the requirement of the operating distance of a thermal infrared imager, guarantees the temperature stability due to the shell with good heat-insulating property, reduces the environmental requirements under the condition of detection, effectively eliminates external interferences such as air circulation, heat conduction, heat radiation and the like, and reduces the space size of the thermal imager under the condition of detection. Moreover, the whole detection device has small volume and is convenient to operate and quick to detect.

Description
