![]() All sensors in this selection have short-wave infrared (SWIR) wavelengths between 850nm, 903nm and 905nm. ![]() The dataset will be extended with the Alpha Prime results when testing has been completed.Īll these sensors correspond to the multi-beam (multi-channel) mechanical scanning type: several pairs of laser diodes and photo-detectors (avalanche photo detector (APD) and single-photon avalanche diode (SPAD)) and corresponding emit-remit optics and mirrors, are rotated by a motor for 360 degrees which defines azimuth, while the vertical angle of a laser and photo-detector pair defines elevation. This sensor was a pre-production model, and was tested to provide a preview for the production 128-line Alpha Prime sensor which was unavailable at the time the experiments were carried out. ![]() ![]() All sensors tested in this study were off-the-shelf production models with the exception of the Velodyne VLS-128. ![]()
