Abstract:
A servo rotary scanning system of three-dimensional holographic imaging may include a servomotor (20) having a first angle sensor (21), a second angle sensor (30), a control component (40), a servo driver (50) and a rotary frame (10), the servo rotary scanning system of three-dimensional holographic imaging is a full-closed loop servo control system, the second angle sensor (30) detects an actual rotating angle of the rotary frame (10) and feeds back a frame feedback signal to the control component (40), an instruction signal in the control component (40) is compared with the frame feedback signal to generate a following error, the first angle sensor (21) detects an output rotating angle of the servomotor (20) and feeds back a motor feedback signal to the servo driver (50), and the servo driver (50) controls the servomotor (20) to rotate according to the following error and the motor feedback signal.
