Observing atmospheric convection with dual-scanning lidars [PDF]
Atmospheric Measurement Techniques, 2023 While convection is a key process in the development of the atmospheric boundary layer, conventional meteorological measurement approaches fall short in capturing the evolution of the complex dynamics of convection. To obtain deeper observational insight

Deploying scanning lidars at coastal sites [PDF]
, 2016 This report presents the concept of scanning lidars placed at coastal sites in order to measure the near-coastal (offshore) wind resource. In particular, the site requirements for such scanning lidars are examined in the context of the siting choices made for the RUNE project.

Alignment of scanning lidars in offshore wind farms [PDF]
Wind Energy Science, 2022 Long-range Doppler wind lidars are applied more and more for high-resolution areal measurements in and around wind farms. Proper alignment, or at least knowledge on how the systems are aligned, is of great relevance here.

Scanning single-pixel imaging lidar
Optics Express, 2022 Long-range light detection and ranging (lidar) of active illumination optical imaging has widespread applications, such as remote sensing, satellite-based global topography, and target recognition and identification. Here, to make trade-offs among imaging efficiency, resolution, receiving field of view, divergence angle, and detected distance, we ...

Gain compensation across LIDAR scans
Computers & Graphics, 2022 High-end Terrestrial Lidar Scanners are often equipped with RGB cameras that are used to colorize the point samples. Some of these scanners produce panoramic HDR images by encompassing the information of multiple pictures with different exposures. Unfortunately, exported RGB color values are not in an absolute color space, and thus point samples with ...
