Abstract

The invention belongs to the technical field of atmospheric infrared detection equipment, and particularly relates to an infrared transmitting device and an infrared receiving device of the atmospheric infrared detection equipment. The overall pitching and left and right sweeping of the infrared detection equipment are achieved through a two-axis turntable. The equipment is simple in transmission structure, good in stability and high in adjustment precision, thus the installation and focusing efficiency and focusing precision of the infrared detection equipment are greatly improved. According to the equipment, a lens is installed on a movable support; the movable support is installed on a slider arranged on the barrel wall of a Casher reflection telescope; the position of the lens in the Casher reflection telescope can be adjusted in real time from the outside of the Casher reflection telescope; the operation is simple and convenient; the equipment assembly and maintenance efficiency are improved; the fast connection and positioning of the Casher reflection telescope and the turntable are achieved by using a dovetail type plug-in structure; the connecting structure is stable and reliable; the installation precision is high.

Description

technical field [0001] The invention belongs to the technical field of atmospheric infrared detection equipment, and in particular relates to an infrared emitting device and an infrared receiving device of atmospheric infrared detection equipment. Background technique [0002] Air pollution is one of the major problems currently facing our country. Continuous online monitoring of ambient air, mastering the emission, diffusion and evolution of pollutant gases, and realizing accurate traceability are of great significance for formulating emission reduction policies, evaluating emission reduction programs, and thoroughly solving air pollution problems. important meaning. Using the "infrared fingerprint" absorption characteristics of the gas to be measured for spectral quantitative analysis to obtain the concentration of the gas to be measured has an important application in the field of online gas detection. Gas concentration detection based on infrared spectroscopy can be div...
