Abstract

The invention discloses a shielding method and device for infrared radiation measurement on a high-back surface, which can effectively ensure measurement accuracy. The shielding method includes the selection of the measurement orientation and measurement equipment, setting the size of the radiation shielding area, selecting and assembling suitable The shielding device, the installation of an infrared radiation measuring instrument and radiation measurement, and the correction of the influence of the shielding device's own radiation on the measurement results, etc. The invention adopts an open radiation shielding device, which can eliminate the influence of environmental radiation on radiation measurement, greatly increase the proportion of the high-back self-infrared radiation in the total radiation received by the infrared detector, and improve the measurement accuracy of the high-back self-radiation.

Description

technical field [0001] The invention relates to the technical field of infrared radiation measurement on object surfaces, in particular to a shielding method and device for infrared radiation measurement on high-reflective surfaces. Background technique [0002] When measuring infrared radiation, the infrared radiation of the surrounding environment is a non-negligible source of interference. Non-blackbody measured objects always have different reflective abilities, and the ambient infrared radiation can enter the infrared radiation measuring instrument after being reflected by the measured object. Only a part of the total radiation received by the infrared radiation measuring instrument comes from the self-radiation of the measured object, and the interference of environmental radiation on the infrared radiation measurement of the high-reverse surface (smooth object surface with high infrared reflectivity) is particularly serious. When the infrared reflectance of the measu...
