Problems solved by technology

[0003] At present, the surface of the surface source blackbody has a repeatable structure arranged in an array. A protruding cone is formed on a plate, however, due to the limitation of the processing capacity of the processing device, the bottom of the adjacent cone is flat and concave, which reduces the emissivity of the surface source blackbody radiation source and affects the surface source blackbody radiation source performance

Embodiment approach 1

[0033] like figure 1 As shown, the top view structural schematic diagram of the surface source black body of the first embodiment of the present invention, from figure 1 It can be seen from the above that the surface source blackbody has a rectangular pyramid arranged in a matrix, and the surface source blackbody is a matrix combination of N rows and M columns, wherein N is an integer greater than 1, and M is also an integer greater than 1. When it is necessary to set a large-area surface source blackbody, set N and M to larger values, so as to obtain a large-sized surface source blackbody, and set different numbers of squares according to the size of the specific surface source blackbody. The cone can obtain surface source blackbodies of different sizes to meet the demand for surface source blackbodies of different calibers.

Embodiment 2

[0038] like Figure 8 Shown is a schematic top view of the surface source blackbody of the second embodiment of the present invention. The second embodiment is the same as the first embodiment, and the description will not be repeated. The surface source black body adopts a matrix structure of N rows and M columns. In a certain row, there is a distance d / 2 between any adjacent quadrangular pyramids , and in the same row, the four-sided pyramid and the holes on the bottom plate are distributed at intervals, the distance between any two adjacent holes is d, and in the previous or next row of the certain row, any adjacent The holes are arranged at a distance of d / 2. like Figure 9 As shown, from the bottom of the bottom plate, it is found that the holes on the bottom plate are arranged crosswise in the row direction and the column direction; Figure 10 It is a schematic diagram of the three-dimensional structure of the surface source blackbody of the second embodiment of the p...

Abstract

The invention provides a surface source black body and a manufacturing method thereof. The surface source black body comprises a base plate and cones. The base plate is used for forming a support structure of the surface source black body. The predetermined number of cones is formed on the base plate. The cones are arranged on the base plate according to a predetermined mode. At least one part of the cones and the base plate form one body. And at least the other part of the cones is formed independently. The manufacturing of the surface source black body is simple. A processing technology is saved and cost is reduced. Manufacturing is convenient and the surface source black body is convenient to rapidly assemble. A large area of the surface source black body can be made. A high emissivity is possessed. And a verification demand of an infrared spectrum segment is satisfied.

Description

technical field [0001] The invention relates to a blackbody, in particular to a surface source blackbody and a manufacturing method. Background technique [0002] As a standard radiation source in the infrared spectrum, the surface source blackbody is widely used in the calibration of infrared remote sensors and thermal imagers. With the development of infrared technology, its application is more and more extensive, and the temperature range is further expanded. Especially with the establishment of the earth observation system, the design caliber of infrared remote sensing cameras is getting larger and larger, and the caliber of area source black bodies is required to be larger and larger. For a surface source blackbody radiation source, its emissivity depends on the surface structure and coating of the surface source. Different surface structures will affect the emissivity of surface source blackbody radiation, and the use of different coatings will also make the blackbody...
