Problems solved by technology
The disadvantage is that the energy stability of the Raman laser produced by this method is poor, and the windows at both ends of the Raman tube are often polluted, which seriously affects the engineering application, and the price of this system is relatively expensive
However, it is not yet possible to achieve high-altitude ozone concentration profiles

Embodiment Construction
[0038] Such as figure 1 As shown, the ultraviolet CCD beam imaging technology detects the ozone concentration height profile device, including a first laser 1, a second laser 2, a first reflector 3, a second reflector 4, an ultraviolet CCD camera 5, and a controller 6. The first laser 1 and the second laser 2 emit similar ultraviolet wavelengths, the first reflector 3 and the second reflector 4 reflect the beams emitted by the corresponding lasers, and the ultraviolet CCD camera 5 receives the light reflected by the two reflectors into the atmosphere beam. The controller 6 is connected with the first laser 1 , the second laser 2 and the ultraviolet CCD camera 5 . The wavelength range of the first laser 1 and the second laser 2 is 260-310 nm, and the wavelength difference between the first wavelength corresponding to the first laser 1 and the second wavelength corresponding to the second laser 2 is 8-12 nm. In this solution, the wavelength difference between the first wavelen...

Description
technical field [0001] The invention relates to the technical field of ozone concentration height profile detection, in particular to an ultraviolet CCD beam imaging technology detecting ozone concentration height profile device and method. Background technique [0002] At present, the instrument for detecting the ozone concentration height profile is the backscattering differential absorption lidar. The detection principle is to use the differential absorption method. The required two beams of pulsed ultraviolet lasers are generally generated by a gas Raman tube. The specific method is that the 266nm pulsed pump laser passes through the deuterium gas and hydrogen Raman tubes to generate Raman lasers with two wavelengths of 289nm and 299nm. The disadvantage is that the energy stability of the Raman laser produced by this method is poor, and the windows at both ends of the Raman tube are often polluted, which seriously affects the engineering application, and the price of thi...
