Embodiment Construction
[0037] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0038] A hyperspectral spectroscopic device for atmospheric detection of the present invention, its structure is as follows figure 1 As shown, it includes a laser receiving and collecting part and a multi-beam reflecting part. It is characterized in that the laser receiving and collecting part includes a three-dimensional translation platform 3, and a double-hole diaphragm 4 is arranged on the three-dimensional translation platform 3. The height of the three-dimensional translation platform 3 can be adjusted. Adjust so that the center of the line of the double-hole diaphragm is positioned on the focal point of the collimating lens, the double-hole diaphragm 4 is vertically arranged, and the side of the double-hole diaphragm 4 has a first through hole 13 and a second through hole 14. The through hole 13 is provided with a first optical fiber 1...
