Laser detection and ranging device

A LADAR device, comprising:

• a rangefinder;
• a signal transmission module;
• a power transmission module;
• a mechanical rotating part;
• a housing;
• a signal processing board;
• and
• a timing module;
• wherein:
• the signal transmission module comprises at least one optical communication transmitter and one optical communication receiver corresponding to the one optical communication transmitter;
• the power transmission module comprises 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 comprises a laser, an emitting lens assembly, a receiving sensor, and a receiving lens;
• the emitting lens assembly comprises a first accommodation space and the laser is disposed in the first accommodation space;
• the receiving lens comprises a second accommodation space and the receiving sensor is disposed in the second accommodation space;
• the at least one optical communication transmitter and one optical communication receiver corresponding to the one optical communication transmitter are disposed in a middle part of the housing;
• the mechanical rotating part comprises a built-in hollow-shaft motor;
• the housing comprises a first part, a second part, and a third part, and the second part is disposed between the first part and the third part;
• the built-in hollow-shaft motor is flexibly connected to the first part of the housing via a belt, and is adapted to drive the first part and the second part of the housing to rotate via the belt;
• the power transmission module comprises an upper part and a lower part;
• the upper part is disposed in the second part of the housing and adapts to rotate axially in 360 degrees;
• and the lower part is fixed on the third part of the housing;
• the rangefinder is a time-of-flight laser ranging module;
• and
• when in use, the signal processing board adapts to produce a pulse signal;
• an optical signal is transmitted from the optical communication transmitter to the optical communication receiver;
• the timing module adapts to receive the pulse signal as a timing start signal, receive a timing termination signal from the receiving sensor, and calculate a time of flight of the optical signal according to the timing start signal and the timing termination signal.
