Detection system of infrared thermal imaging equipment

Abstract

The invention provides a detection system of infrared thermal imaging equipment. The system comprises a target, a background blackbody, a temperature detection component, a temperature regulation component and a control component, wherein current temperature of the target and current temperature of the background blackbody are collected; the temperature regulation component is used for raising orlowering the current temperature of the background blackbody; and the control component controls the temperature regulation component to regulate the current temperature of the background blackbody, so that when a current temperature difference between the target and the background blackbody is consistent with a set target temperature difference, the to-be-detected infrared thermal imaging equipment generates a thermal image, and a detection result is obtained according to the thermal image. Through the system in the embodiment, the infrared thermal imaging equipment can directly generate thethermal image of the target without a collimation optical system, the thermal image is used for a detector to observe and detect comprehensive parameters of the target, the problems that other infrared thermal imaging equipment detection systems are inconvenient to carry and use in an external field, difficult to use in in-situ detection, high in price, low in precision and the like are effectively solved, and the system is simple in structure and easy to realize.

Description

technical field [0001] The invention relates to the technical field of infrared thermal imaging equipment, in particular to a detection system of infrared thermal imaging equipment. Background technique [0002] The comprehensive parameters of infrared thermal imaging equipment include NETD (noise-equivalent temperature difference, hereinafter referred to as noise-equivalent temperature difference), MRTD (minimum resolvable temperature difference, minimum resolvable temperature difference) and MDTD (minimum detectable temperature difference, minimum detectable temperature difference). At present, the same detection equipment with collimating optical system is used to complete the detection of these three parameters at home and abroad, but the shape of the target is different. The basic components of the device include a target, a background blackbody, an electronic system for temperature measurement and temperature control of the target and the background blackbody, and a co...
