Embodiment Construction

[0014] The present invention is further described in conjunction with accompanying drawing:

[0015] An energy-adjustable infrared target simulation system, such as figure 1 As shown, it includes: black body 1, energy diaphragm 2, illumination lens 3, infrared homogenization system 4, infrared target 5 and projection lens 6, the infrared radiation emitted by black body 1 passes through energy diaphragm 2 and is collimated by illumination lens 3 Afterwards, it is irradiated on the infrared dodging system 4, and then the infrared target 5 is irradiated after the dodging, and the output is collimated through the projection lens 6. The exit surface of the black body 1 is located on the focal plane of the illumination collimating lens 3 ; the infrared target 5 is located on the focal plane of the projection lens 6 . The blackbody 1 can be cavity blackbody or surface source blackbody, and the energy aperture 2 is a circular adjustable aperture. The output energy of the blackbody 1 ...

Abstract

The invention discloses an energy-adjustable infrared target simulation system, which belongs to the field of optical techniques, and relates to a broadband and energy-adjustable-continuously infrared target simulation system. The infrared target simulation system comprises a black body 1, an energy diaphragm 2, a lighting lens 3, an infrared dodging system 4, an infrared target 5 and a projection lens 6, wherein the infrared radiation emitted by the black body 1, after passing through the energy diaphragm 2 and being collimated by the lighting lens 3, enters the infrared dodging system 4; then, after being dodged by the infrared dodging system 4, the infrared radiation enters the infrared target 5 and finally is collimated and outputted by the projection lens 6. The emergent face of the black body 1 is arranged on the focal plane of the lighting collimating lens 3; and the infrared target 5 is arranged on the focal plane of the projection lens 6, and the emergent energy of the target is controlled by the energy diaphragm 2, when the diaphragm largens, the system energy increases, and when the diaphragm is reduced, the system energy decreases. According to the invention, the energy adjustment on an infrared target simulator is performed by using a diaphragm structure, so that the continuous change of infrared broadband energy can be realized, therefore, the system can carry out simulation test on the infrared systems under different energy requirements.

Description

technical field [0001] The invention belongs to the field of optical technology and relates to an infrared target simulation system with wide band and continuously adjustable energy. Background technique [0002] In the infrared simulation system, the infrared target simulator is used to provide an infrared target source, and all tests are carried out around the characteristics of the infrared target simulator. The infrared target simulator consists of a target source and a projection lens, which projects the target source image to infinity. In the simulation test, it is usually necessary to adjust the energy of the infrared target, and test the seeker under different energy conditions to study the response of the seeker to the target at different target distances and different weather conditions. Since the temperature of the blackbody reflects the temperature characteristics of the target, the energy attenuation of the target should not be realized by changing the temperat...
