Abstract

The invention provides a device and a method for measuring the atmospheric transmissivity by an optical radiation measurement instrument. The device comprises a total diffuse reflection element, a shading element, the optical radiation measurement instrument and a computing element, wherein the total diffuse reflection element is used for carrying out diffuse reflection on sun light according to the preset angle so as to enable the sun light to be reflected into the optical radiation measurement instrument; the shading element is capable of keeping out the sun light irradiating the total diffuse reflection element when being arranged at a preset position; the optical radiation measurement instrument is used for measuring the total diffuse reflection element to acquire first response data containing total diffuse reflection sun light, and second response data which does not contain the total diffuse reflection sun light; the computing element is used for calculating the response difference between the first response data and the second response data; the whole layer atmospheric transmissivity at the response spectrum section of the optical radiation measurement instrument on the current measurement path can be obtained according to the response difference and the response data known in advance of the total diffuse reflection sun light positioned outside the atmospheric layer. The device and the method aim at accurately obtaining the whole layer atmospheric transmissivity at the response spectrum section of the optical radiation measurement instrument on the measurement path formed by the sun and the measuring device.

Description

technical field [0001] The invention relates to the fields of optical radiation measurement and atmospheric measurement, in particular to a device and method for measuring atmospheric transmittance based on an optical radiation measuring instrument. Background technique [0002] Optical measurements using optical radiometers are commonly used. When an optical radiometer measures visible light photometry and infrared radiation of a distant target, it is necessary to know the atmospheric transmittance of the response spectrum of the optical radiometer on the measurement path to correct the attenuation effect of the atmosphere on the radiation of the measured target. [0003] In the prior art, the atmospheric optical parameters are usually obtained by auxiliary atmospheric parameter measurement equipment, and then the obtained atmospheric optical parameters are input into the atmospheric transmission calculation software, and the atmospheric transmission calculation software ob...
