High-emissivity surface source black body radiator and manufacturing method thereof

Abstract

The invention provides a high-emissivity surface source black body radiator and a manufacturing method thereof. The high-emissivity surface source black body radiator comprises the components of a base board which is used for forming the supporting structure of a surface source black body; a preset number of cones which are formed on the base board, wherein the cones are distributed on the base board in a preset manner. The cones and the base board are in an integrated structure. Conical grooves are arranged between the adjacent cones. The conical grooves are non-flat and concave. The high-emissivity surface source black body radiator has advantages of easy manufacture, effective machining process saving, effective cost reduction, convenient manufacture and convenient expansion. The high-emissivity surface source black body radiator can be manufactured to a large-area surface source black body and has high emissivity. Furthermore a calibration requirement for an infrared spectral band is satisfied.

Description

technical field [0001] The invention relates to a blackbody, in particular to a high-emissivity surface source blackbody radiation source 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 coat...

AI Technical Summary

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
