Embodiment 1
[0053] A radial plume multi-component gas measurement remote sensing system such as figure 1 As shown, the number of two lasers is 2. For the convenience of description, the devices that only match the first laser are represented by A, and the devices that are only matched with the second laser are represented by B. Multiple laser systems Except for shared devices, this system includes reflected laser acquisition unit and data acquisition unit;
[0054] The data acquisition unit includes an interconnected data acquisition card and a computer. The data acquisition card 1 can realize functions such as data acquisition and A / D conversion, and transmit the collected photoelectric signal to the computer for calculation and analysis in the computer. The computer at the office is a portable computer, and the reflective laser acquisition unit includes two lasers connected to the data acquisition card, which are laser A2 and laser B21 respectively. The reference absorption cell A4 is ...
Embodiment 2
[0058] A radial plume multi-component gas measurement remote sensing system, the structure is as shown in embodiment 1, the difference is that a vertical scanning mirror (not shown in the figure) is also arranged between the beam expander 8 and the cooperative target reflector 9 Out), the light beam is irradiated to the cooperative target reflector 9 through the vertical scanning mirror along the beam expander 8, and then irradiated to the reflector 10 through the vertical scanning mirror, and converged to the grating 20 through the first lens 11;
[0059] A plurality of lasers, and a beam splitter, a reference absorption cell, a first detector, a beam combiner, a beam expander, a vertical scanning mirror, a reflection mirror, a first lens, a grating, a narrowband filter, and a beam splitter respectively connected to the plurality of lasers, Both the second lens and the second detector are integrated into an integral structure 22, and are arranged on a horizontal rotating platf...
Embodiment 3
[0062] A radial plume multi-component gas measurement remote sensing system, the structure of which is shown in Example 2, the difference is that the vertical scanning mirror is a rotating prism, and its function is to irradiate the horizontal beam to the cooperation target far above or below reflector, and then through the vertical scanning mirror, the light beam is irradiated onto the reflector, and the gas concentration measurement is realized when the cooperative target reflectors are vertically distributed.
