Abstract

LED mini-lidar is a new concept optical sensor, not to be replaced from the traditional lidar with laser light source. To use this lidar in near range, several lidar parameters were rearranged due to the new concept. LED device is tough against rough treatment. It has wide color variation including NUV and NIR regions. Its beam is hard to collimate because of LED lamp size, while its power is estimated to be enough to monitor the atmosphere and dusts for a few hundred meters. LED mini-lidar has a high repetition frequency of more than 100kHz to accumulate weak lidar echoes. The original photon counter was designed to follow the high repetition frequency. The several types of LED lidars were developed to monitor air motion and dust flow.
