LD19 is mainly composed of a laser ranging core, wireless transmission unit, wireless communication unit, angle measuring unit, motor driving unit, and mechanical housing. The LD19 ranging core adopts DTOF technology to measure 4500 times each second. When it works, LD19 emits the infrared laser forward, and the laser is reflected to the single photon receiving unit after encountering the target object. Thus, we get both times of laser emitting and receiving, the gap between them is the time of flight. With the light speed, we can calculate the distance. After receiving distance data, LD19 will combine them with angel value getting from the angle measurement unit to comprise the points cloud data, then transmit the points cloud data to an external interface via wireless communication. Meanwhile, the external interface provides PWM to allow the motor driving unit to drive the motor. After the external control unit gets the rotational speed, it will reach to specified speed through PID algorithm closed-loop control to ensure LD19 works stably.
