Combined-type standard testing source and method for infrared sensor

Abstract

The invention relates to the technical field of infrared imaging testing, and specifically relates to a combined-type standard testing source and method for an infrared sensor. The combined-type standard testing source is formed by the combination of a multi-mode black body and a standard black body. The biggest characteristic of the combined-type standard testing source is that the combined-type standard testing source guarantees that the temperature difference of all testing targets in a constant temperature box can nearly be neglected through the constant temperature box (multi-mode black body) capable of controlling temperature at high precision and the arrangement of the plurality of testing targets in the constant temperature box, improves the testing calibration precision, and meets different testing requirements. Meanwhile, the multi-mode black body and the standard black body are combined, thereby meeting the requirements of the conventional testing of the infrared sensor, and solving problems of temperature measurement calibration and image calibration of the infrared imaging sensor. The standard testing source achieves the automatic operation through a streamline-type transmission device, and greatly improves the testing efficiency.

Description

technical field [0001] The invention relates to the technical field of infrared thermal imaging testing, in particular to an infrared sensor combined standard testing source and testing method. Background technique [0002] The infrared sensing system is a measurement system using infrared rays as the medium. There are more than one hundred related test items. The whole system is very complicated and expensive, especially the standard reference source for testing, which requires many independent test targets. Slight differences in the temperature of each test target during the test will directly affect the calibration accuracy of the infrared thermal imaging sensor, thereby affecting the final product index, so it is necessary to accurately control the temperature of the test target.

Problems solved by technology

[0003] In the traditional technical solution, it is generally a plug-in type, that is, one test target is used, and it needs to be pulled out after use, and then another test target is inserted for testing. The disadvantage of this technical solution is that the temperature is unstable during replacement, and the cost is high. , large size, and there is no uniform standard among independent devices, and pipeline testing cannot be performed quickly, so a highly integrated smart device is needed to solve the above problems
