In the field of atmospheric observation, clouds serve as a "barometer" of meteorological changes. The accurate acquisition of data such as height, thickness, and cloud cover is directly related to the scientific decision-making in many fields such as aviation safety, weather forecasting, and environmental monitoring. As a back-scattering lidar device based on the advanced meter scattering principle, the 1G portable laser cloud meter carries powerful performance in a compact body, breaking the space limitations and operational barriers of traditional cloud measuring equipment, and becoming a "decoding tool" for high-altitude weather in various scenes.
1. Core technical principle: use laser as pen to draw a cloud map

The core working logic of the 1G portable laser cloud meter relies on the mature dual principles of meter scattering and laser time-of-flight methods. The equipment emits highly stable infrared laser pulses to high altitudes. When the beam passes through the atmosphere and encounters particles such as cloud droplets and aerosols, it will generate backscattered signals. Highly sensitive optical receivers accurately capture these weak signals and convert them into electrical signals. The precision timing module is used to measure the time difference between laser emission and echo reception, and the round-trip path length is deduced based on the speed of light constant. After algorithm correction, the vertical height of the cloud base is obtained, realizing full-link automated processing from "signal capture" to "data output".

Compared with traditional visual inspection or fixed equipment, this instrument has multi-layer cloud penetration measurement capabilities. The laser pulse can penetrate low-level clouds and continue to interact with high-level clouds. By analyzing the intensity and time difference of multiple sets of echo signals, it can simultaneously identify the boundaries, thickness and distribution patterns of multi-layer clouds. It can monitor up to 5 layers of cloud structure, making it possible to conduct three-dimensional observations under complex meteorological conditions. At the same time, the built-in dynamic calibration algorithm can compensate for interference factors such as atmospheric refractive index and temperature drift in real time to ensure data consistency and reliability in different environments.
