We are a group of scientists from the Biology and Physics Department at Lund and Copenhagen University that have been working interdisciplinary towards developing novel optical systems to monitor small insects in their natural environment. Specifically, during the last years our group has worked with the remote monitoring of atmospheric fauna based on the spectral backscattered signal from atmospheric animals We have previously been using Laser-radar or lidar to capture signals, which is an optical remote sensing technology to measure the distance to, or other properties of, targets with laser light and analysing the backscattered light over far distances. In 2013, our research group has invented a novel laser-radar scheme for monitoring of atmospheric fauna.
Novel laser-radar scheme
The novelty consists of implementing a bi-static lidar with a compact and continuous wave laser-diode and a fast line-scan camera. The main aim with the present proposal is use the novel system during the field season 2014 to monitor insects in nature (and to relate their movement patterns and activity cycles to environmental variables, such as e.g. sunlight, temperature, wind speed.)
Weather denotes a compact weather station, All-sky denotes an all sky camera, DAQ is a data acquisition board for wing beat measurements, Quad is a quadrant detector for recording harmonics and heading direction, LD is a Laser Diode, Line is a line scan camera, Cam is a high speed RGB camera. Measurements can be done between 1-20 m. The system can be applied close to ground for horizontal sounding or be put in contact with the water surface for nadir sounding.
The target species to test our setup in the previous image will be disease vectors (Culicoides and mosquitoes), which represent two of the core study systems of our groups. For the disease vectors, the first goal is to determine the signal variation within and between species and sexes of the two important disease vectors, Culicoides obsoletus and C. pulicaris.
