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