Embodiment Construction

[0018] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0019] As a standard infrared radiation source, blackbody is widely used in the calibration and calibration of targets. Especially in the field of aviation, to quantitatively detect the performance of infrared guided missiles, the black body as a standard radiation source is essential. When it is necessary to simulate targets with different distances and different energies, the temperature and aperture of the blackbody are required to be adjustable. For this purpose we provide an aperture black body, such as figure 2 and image 3 As shown, the aperture blackbody can adjust its temperature and aperture according to the distance and energy of the simulated target. The aperture blackbody comprises a blackbody cavity and a blackbody panel, the blackbody panel is provided with openings, the radiation holes of the blackbody cavity and the open...

Abstract

The invention relates to a diaphragm black body, and belongs to the technical field of infrared optics. The diaphragm black body comprises a black body cavity and a black body panel. A radiation hole formed in the black body cavity and a hole formed in the black body panel are located on a same axis. A diaphragm disk and a regulating unit are further arranged between the black body cavity and the black body panel. Diaphragm holes with hole diameters in different sizes are formed in the diaphragm disk in a spaced mode. Under the driving of the regulating unit, the diaphragm holes with hole diameters in different sizes and formed in the diaphragm disk are located on the same axis as the radiation hole formed in the black body cavity and the hole formed in the black body panel do. Due to the fact that the diaphragm disk and the regulating unit are further arranged between the black body cavity and the black body panel, and under the driving of the regulating unit, the diaphragm holes with hole diameters in different sizes and formed in the diaphragm disk can be located on the same axis as the radiation hole formed in the black body cavity and the hole formed in the black body panel do, the black body diaphragm holes can be regulated; and meanwhile, through the arrangement of a temperature control unit which is used for controlling over the temperature of the black body cavity, targets with different distances and energies can be simulated.

Description

technical field [0001] The invention relates to an aperture black body, which belongs to the technical field of infrared optics. Background technique [0002] As a standard infrared radiation source, blackbody is widely used in the calibration and calibration of targets. Especially in the field of aviation, to quantitatively detect the performance of infrared guided missiles, the black body as a standard radiation source is essential. When it is necessary to simulate targets with different distances and different energies, the temperature and aperture of the blackbody are required to be adjustable. However, the diaphragm hole and blackbody temperature of the diaphragm blackbodies currently on the market are not adjustable. Contents of the invention [0003] The object of the present invention is to provide a black body with a diaphragm to solve the problem that the aperture of the black diaphragm cannot be adjusted at present. [0004] In order to solve the above techni...
