Self-cleaning and anti-interference method for laser raindrop spectrometer

Abstract

The invention relates to the technical field of atmospheric sciences and environmental sciences and discloses a self-cleaning and anti-interference method for a laser raindrop spectrometer. The self-cleaning and anti-interference method comprises the following steps: 1) taking down glass substrates from an emitter end and a receiver end of the laser raindrop spectrometer; 2) adding water into hydrofluoric acid, thereby preparing a hydrofluoric acid solution in concentration of 40%; 3) placing the glass substrates acquired in the step 1) into the hydrofluoric acid solution, soaking and cleaning, and then taking out and standing by after cleaning. According to the self-cleaning and anti-interference method for the laser raindrop spectrometer, a rare earth element modified nanometer lyophobicchemical coating layer is respectively coated on the glass substrates; the coating layer has hydrophobicity and cleanability, so that the coating layer is capable of resisting against interference offog drops and decomposing pollutants, so as to achieve a self-cleaning purpose; the coating layer has the advantage of capability of obviously increasing measurement capability and measurement accuracy of the laser raindrop spectrometer.

Description

technical field [0001] The invention relates to the technical fields of atmospheric science and environmental science, in particular to a self-cleaning and anti-interference method for a laser raindrop spectrometer. Background technique [0002] Rainfall information is an important indicator for applications such as meteorological monitoring, airport observation systems, traffic control, and scientific research. Raindrop spectrum is an important content of rainfall information, and it is also one of the important hotspots in the current study of cloud precipitation physics. Therefore, there are currently many raindrop Spectrum measuring instrument. [0003] In general, the use environment of laser raindrop spectrum is in the field, which is affected by atmospheric temperature, humidity and air pollution components. In addition, if the observation is in some foggy field, it will also be affected by fog. Through the use of laser raindrop spectrometer in the field and literatu...
