Spectroscopy Detection and Imaging System Based on Line Array Single Photon Detectors

Boundary layer height is important for weather forecasting and climate studies, but consistent global observations remain difficult. We designed a spaceborne lidar and validated its performance through theoretical simulations and experiments with a scaled airborne prototype. Nighttime results in Yulin agreed closely with ground-based observations, while daytime tests in Hainan showed detection potential under strong background illumination, supporting future global monitoring from space.
