A simplified imaging model of bi-telecentric lenses under Scheimpflug condition and its calibration

International Conference on Photonics and Optical Engineering and the Annual West China Photonics Conference, 2021
In the lens-based imaging model, the Scheimpflug principle is expressed as the object plane, the image plane, and the lens plane intersect in a line. With this principle, the object surface in front of the lens can be tilted by installing a tilted sensor,

Comparison studies of the Scheimpflug lidar technique and the pulsed lidar technique for atmospheric aerosol sensing.

Applied Optics, 2019
The Scheimpflug lidar (SLidar) technique has been recently developed for various remote sensing applications, where the lidar signal is detected by an image sensor according to the Scheimpflug principle instead of the time-of-flight principle. Comparison

Three-wavelength polarization Scheimpflug lidar system developed for remote sensing of atmospheric aerosols.

Applied Optics, 2019
Multiple-wavelength polarization lidar techniques have been of great interest for the studies of aerosol backscattering color ratio, Ångström exponent, particle size distribution, hygroscopic growth, etc. Conventional lidar techniques are mainly based on

Applications of the Scheimpflug Lidar Technique in Atmospheric Remote Sensing

2019 PhotonIcs & Electromagnetics Research Symposium - Spring (PIERS-Spring), 2019
Atmospheric lidar techniques, featuring high spatiotemporal resolution, and high sensitivity, have been widely used for atmospheric aerosol, trace gases, temperature and wind speed measurements since decades. The Scheimpflug lidar technique, based on the
