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

The infrared target simulation system that a kind of energy is adjustable

Technical field

Background technology

In the infrared simulation system, infrared target simulator is used to provide an infrared target source, and all tests all center on the characteristic spread of infrared target simulator.Infrared target simulator is made up of target source and projection lens, and projection lens arrives infinite distant place with the target source image projection.In l-G simulation test, need regulate the energy of infrared target usually, target seeker is tested under the different-energy condition, with the reaction to target under different target distance, different weather state of research target seeker.Because the temperature of black matrix is reflecting the temperature characterisitic of target, thereby the target energy decay should not realize through changing blackbody temperature.Conventional infrared energy is regulated has dual mode: a kind of is through neutral attenuator, and another kind is through the polarization fading sheet.All there is certain limitation in the use in two kinds of methods of adjustment.The transmitance of the outer attenuator of dimethyl diaminophenazine chloride generally becomes with wavelength, can not realize that broadband evenly decays; And the polarization fading sheet is made up of two linear polarizer, has absorbed about 50% target energy near that a slice polaroid of infrared target, and need cool off polaroid in higher-energy state could operate as normal.

Summary of the invention

Infrared target simulator is difficult to realize infrared broadband energy adjustable this limitation continuously under the prior art in order to solve; The invention provides the adjustable infrared target simulation system of a kind of energy, comprise black matrix, energy diaphragm, illumination camera lens, infrared even photosystem, infrared target and projection lens, the infrared radiation that black matrix sends; Through the energy diaphragm; Shine behind the illuminated camera lens collimation on the infrared even photosystem, shine infrared target behind the even light, through crossing the output of projection lens collimation.

The exit facet of black matrix is positioned on the focal plane of illumination collimation camera lens; Infrared target is positioned on the focal plane of projection lens, and cavate black matrix or extend blackbody can be selected for use in black matrix, and the energy diaphragm adopts circular adjustable diaphragm, and black matrix outgoing energy is through the control of energy diaphragm, and when diaphragm became big, system capacity increased, otherwise reduces.

The structure of illumination camera lens and projection lens is transmission-type structure or reflective structure; Said transmission-type structure is made up of a slice lens or multi-disc lens; Reflective structure is made up of a slice catoptron or multi-disc catoptron, and the focal power of illumination camera lens is being for just, and the focal power of projection lens is for just.

Infrared even photosystem is the frosted glass of infrared transmission material, and said infrared even photosystem is a smooth flat facing to a side of illumination camera lens, and a side that faces toward infrared target is a uneven surface.

The material of infrared even photosystem can be selected CaF2 according to service band, BaF2, Ge, Si, ZnS or, ZnSe.

Beneficial effect: the present invention utilizes mechanism of diaphragm to carry out the energy adjustment of infrared target simulator, can realize that infrared broadband energy changes continuously, can under different-energy requires, carry out l-G simulation test to infrared guidance system.
