Inelastic hyperspectral Scheimpflug lidar for microalgae classification and quantification

open access: closedApplied Optics, 2021
An inelastic hyperspectral Scheimpflug lidar system was developed for microalgae classification and quantification. The correction for the refraction at the air–glass–water interface was established, making our system suitable for aquatic environments.

The Scheimpflug lidar method

open access: closedLidar Remote Sensing for Environmental Monitoring 2017, 2017
The recent several years we developed the Scheimpflug lidar method. We combined an invention from the 19th century with modern optoelectronics such as diode lasers and CMOS array from the 21st century. The approach exceeds expectations of background suppression, sensitivity and resolution beyond known from time-of-flight lidars.

Overwater light-sheet Scheimpflug lidar system for an underwater three-dimensional profile bathymetry

open access: closedApplied Optics, 2019
The feasibility of an overwater light-sheet Scheimpflug lidar system for underwater three-dimensional (3D) profiling is considered. Corrections for the refraction at the air-water interface are proposed. Applications for profiling marine ecosystems are explored in distance up to several meters, and millimeter precision is accomplished. The experimental

High Spectral Resolution Scheimpflug Lidar for Atmospheric Aerosol Sensing

Laser & Photonics Reviews
Abstract High spectral resolution lidar (HSRL) can accurately retrieve aerosol optical properties by separating aerosol Mie‐scattering signal from molecular Rayleigh‐scattering signal, but primarily confined to UV–vis region, limiting reliable derivation of aerosol microphysical properties across broader spectral ...

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 the time-of-flight principle.
