Abstract

The invention discloses infrared real-time test equipment based on iOS wireless receiving and sending. The infrared real-time test equipment is composed of a target generating unit, a portable black body, a sending unit, a signal switching box, a receiving and processing unit and an iPad2 or iPhone4, wherein the signal switching box can achieve wireless sending. An infrared target radiation source generated by the black body is observed by a tested system, the signal switching box is connected with the tested system, an infrared test image output by the tested system is converted into wireless signals sent to embedded test software operating in an iOS system, and finally the software displays the infrared image and a test result on a touch screen or stores the infrared image and the test result to a local hard disk in real time. The infrared real-time test equipment can conduct real-time test on performance on a large-distance infrared imaging system in a field environment particularly, the weight of the whole equipment is about 6 kg, no connection wire is needed, and the equipment is good in flexibility and high in portability.

Description

technical field [0001] The invention relates to an infrared real-time testing device, which can especially test the performance index of an infrared imaging system in real time in a field environment. Background technique [0002] Performance evaluation of infrared imaging system is one of the overall technical requirements of the system, and plays an important role in system design and analysis. Under normal circumstances, these performance indicators are tested and evaluated in a laboratory environment; at present, mainstream foreign test equipment includes DT (variable target test system), LAFT (movable variable distance test system) and SAFT of INFRAMET [1]. (Moveable variable distance / target test system); I-SITETM photoelectric test system of Optikos [2]; Infrared / Visible Test Station of EO [3] and infrared system test software IRWindows of SBIR [4] TM 2001. The test software of these test equipment generally adopts the framework of PC + Windows7, and the portability ...
