TLDR
In this paper, the authors present recent advances and applications of profiling biological targets with Scheimpflug lidar and demonstrate applications for profiling the aerofauna and classifying various groups of species.Abstract:
Here we present recent advances and applications of profiling biological targets with Scheimpflug lidar. In particular we demonstrate applications for profiling the aerofauna and classifying various groups of species. Based on lidar data over the Ivorian countryside we investigate range dependent detection limits by comparing data with distinct sample rates and pulse energies.read more

Super Resolution Laser Radar with Blinking Atmospheric Particles - Application to Interacting Flying Insects
TL;DR: In this paper, a laser-radar system for field entomology based on the so-called Scheimpflug principle and a continuous-wave laser was developed, where the sample-rate of this method is unconstrained by the roundtrip time of the light, and the method allows assessment of the fast oscillatory insect wing-beats and harmonics over kilometers range, e.g., for species identification and relating abundances to the topography.

TL;DR: In this paper, a continuous-wave lidar system was used to monitor the flying insect diurnal activity and also the influence of changes in weather conditions, e.g., the occurrence of rain.

TL;DR: The results of the first Lidar study applied to continuous and simultaneous monitoring of aerial insects, bats and birds in China illustrate how common patterns of flight activity, e.g. insect swarming around twilight, depend on predation risk and other constraints acting on the faunal components.

Photonic Monitoring of Atmospheric and Aquatic Fauna
TL;DR: In this paper, the emerging field of optics and laser-based monitoring of flying fauna is reviewed with an emphasis on remote sensing based on pulsed and contineous wave (CW) lidar systems, and how they complement existing radar techniques.
