Scheimpflug-like processing of differential absorption lidar data on water vapor [PDF]
EPJ Web of ConferencesDifferential Absorption Lidar (DiAL) method is widely used for a number of ground-based and airborne greenhouse gas measurement applications. However, for a direct detection in the 2µm range, other sources of random noise can be neglected in front of the

Optics Express, 2018 In this paper, a new prototypical Scheimpflug lidar capable of detecting the aerosol extinction coefficient and vertical atmospheric transmittance at 1 km above the ground is described. The lidar system operates at 532 nm and can be used to detect aerosol extinction coefficients throughout an entire day. Then, the vertical atmospheric transmittance can

Oil pollution discrimination by an inelastic hyperspectral Scheimpflug lidar system
Optics Express, 2017 An inelastic hyperspectral Scheimpflug lidar system is developed for range-resolved oil pollution detection and discrimination. A theory of system parametric design is built for aquatic circumstances, and laser-induced fluorescence spectra with an excitation wavelength of 446 nm are employed to detect oil pollution.

Atmospheric CO2 sensing using Scheimpflug-lidar based on a 157-µm fiber source
Optics Express, 2019 A molecular laser-radar system, based on the Scheimpflug principle, has been constructed and demonstrated for remote sensing of atmospheric CO2 concentrations using Differential Absorption Lidar (DIAL) in the (30012←00001) absorption band. The laser source is a Continues Wave (CW) Distributed-FeedBack (DFB) diode laser seeding an Erbium-doped fiber ...

A Scheimpflug lidar used to observe insect swarming at a wind turbine
Ecological Indicators, 2020 Abstract Wind turbines have considerable impact on flying animals, particularly bats, which are sometimes killed in large numbers by the moving rotors. A longstanding question remains why bats are attracted to wind turbines and risk their lives among the moving rotor blades.

African Journal of Tropical Entomology ResearchVector monitoring remains a challenging task for large-scale continuous surveillance. Light Detection and Ranging (Lidar) systems, which use laser pulses to detect and characterize objects at a distance (Lidar systems), offer a solution by capturing the wingbeat modulation frequencies of flying insects, especially mosquitoes.

Light-sheet based two-dimensional Scheimpflug lidar system for profile measurements
Optics Express, 2018 This work presents a novel concept for 2D Scheimpflug lidar. A light-sheet based 2D Scheimpflug lidar system is developed and realized for surface profile measurements. The theory of a geometrical relationship underlying the system is developed, and the possibility of 3D profile measurements for a plastic bowl, a rhombic carton box and a manikin are ...
