Problems solved by technology

This method makes up for the shortcomings of the first two measurement methods, but from a structural point of view, the distance between the sampling aerosol and the elliptical mirror is relatively close, and it is easy to pollute the mirror after long-term work. In addition, the aspheric mirror is difficult to process and expensive, so it is not suitable for promotion.

Embodiment Construction

[0032] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] see figure 1 As shown, the aerosol scattering phase function observation device of this embodiment includes main components such as a laser 3 , a sample receiving chamber 2 , an imaging device 9 , and a processing unit (not shown in the figure). Wherein, the laser is used as the emitting light source for emitting the laser beam. Because the laser has the characteristics of good monochromaticity and small divergence angle, the use of laser to irradiate the atmosphere and aerosol in the environment to be tested can reduce the interference caused by stray light on the test results. Inject the gas sample of the environment to be tested into the sample receiving chamber 2, and irradiate the gas sample in the sample receiving chamber 2 with the laser beam emitted by the laser 3, when the laser beam irradiates the atmosphere and aerosol in th...

Abstract

The invention discloses an aerosol scattering phase function observation device and an observation method. The device uses a laser as a light source, emits a laser beam to irradiate the atmosphere and aerosol in the environment to be measured, and uses an imaging device as a receiving end to collect the laser beam to irradiate the atmosphere. The scattered light generated by the aerosol and the aerosol then forms a grayscale image. By processing the grayscale image, the aerosol scattered light sequence is calculated, and the aerosol scattering phase function satisfies the normalized characteristics, and the inverse calculation can be performed. aerosol scattering phase function. The sol scattering phase function observation method proposed by the present invention is different from the prior art, has high sensitivity, strong real-time performance, simple device structure and low cost, and can be widely used in aerosol observation devices, such as aerosol laser radar and atmospheric visibility instrument , aerosol particle spectrometer, etc., to provide data comparison and data reference.

Description

technical field [0001] The invention belongs to the technical field of gas detection, and in particular relates to a device and a method for detecting aerosols in an atmospheric environment. Background technique [0002] Atmospheric aerosol is a mixed system of particles with certain stability and low settling velocity in the gas and gravitational field. It is a multiphase system composed of solid and liquid particles such as clouds and ice crystals. Atmospheric aerosol, as an important part of the earth-atmosphere system, is an important factor in climate effects. It not only directly affects the radiant energy budget of the earth-atmosphere system, but also indirectly affects climate by changing the lifetime of clouds in the atmosphere. At the same time, the study of optical characteristics such as scattering and absorption of atmospheric aerosols and the temporal and spatial distribution characteristics of aerosols is a hot topic in the research of climate effects and en...
