Abstract
A LADAR device, including: a rangefinder; a signal transmission module; a power transmission module; a mechanical rotating part; a housing; a signal processing board; and a timing module. The signal transmission module includes at least one optical communication transmitter and one optical communication receiver. The power transmission module includes coupled magnet rings and communicates with the signal transmission module through electromagnetic induction to achieve wireless power transmission. The mechanical rotating part is adapted to drive the rangefinder to rotate axially in 360 degrees. The rangefinder is disposed on the housing, and includes a laser, an emitting lens assembly, a receiving sensor, and a receiving lens. The emitting lens assembly includes a first accommodation space and the laser is disposed in the first accommodation space. The receiving lens includes a second accommodation space and the receiving sensor is disposed in the second accommodation space.
