LIDAR, TRANSMITTER AND RECEIVER

The invention discloses a laser radar, a receiver used for receiving laser and an emitter used for emitting laser, the emitter adopts a plurality of light-emitting areas, the light-emitting areas comprise at least one first light-emitting area and at least one second light-emitting area, and the first light-emitting area and the second light-emitting area are arranged in the first light-emitting area and the second light-emitting area. The power of the laser emitted by the first light-emitting area is greater than that of the laser emitted by the second light-emitting area, and the first light-emitting area and the second light-emitting area emit the laser at different time. According to the method and the device, the problem that a short-distance blind area is caused by submerging a short-distance target when the laser radar reaches a farther detection distance by improving the power in the prior art is solved, so that the problem of the short-distance blind area caused by long-distance detection is solved t
