Device for enabling the alignment of a transmitting and receiving channel of a LIDAR device and a LIDAR device equipped with such a device

摘要

Device for enabling the alignment of a transmission and reception channel of a transmission channel with means (1, or 1 and 2) for generating and transmitting a laser beam (FT) in a defined direction having LIDAR device, the device having a reception channel with optical means (4, 5), which have a parabolic mirror (4) and a focal correction device (5), and which optical means are provided and oriented in order to generate a backward laser beam (FR) obtained by reflection from a cloudiness in the atmosphere or on the ground. the LIDAR device having main measuring means (3) for receiving the backward laser beam (FR) on at least one transducer, and wherein the device has auxiliary measuring means (7) which use at least one component of the backward laser beam (FR) allow to determine the centering of the optical means (4, 5) on the backward laser beam (FR), characterized thereby t, that the auxiliary measuring means (7) are formed by sensors (7) which are located at defined points in a peripheral zone of a beam or ...
