Abstract Aerosols and clouds greatly affect the Earth’s radiation budget global climate. Light detection ranging (lidar) has been recognized as a promising active remote sensing technique for vertical observations of aerosols clouds. China launched its first space-borne aerosol-cloud high-spectral-resolution lidar (ACHSRL) on April 16, 2022, which is capable high accuracy profiling around globe.

To fill gap insufficient...
One of the challenges in surface defects evaluation large fine optics is to detect microns on surfaces tens or hundreds millimeters. Sub-aperture scanning and stitching considered be a practical efficient method. But since there are usually few aperture optics, resulting no only one run-through line feature many sub-aperture images, traditional methods encounter with mismatch problem. In this paper, feature-based multi-cycle image algorithm proposed solve The overlapping areas sub-apertures...
