Servo rotary scanning system of three-dimensional holographic imaging

A servo scanning system of three-dimensional holographic imaging, comprising:

• a fixing support comprising:
• an upper mounting arm;
• a lower mounting arm spaced from the upper mounting arm;
• and
• supporting columns connecting the upper and lower mounting arms to define a space;
• a frame mounted in the space and capable of rotating about an imaginary axis relative to the fixing support, the frame comprising:
• a first cross arm coupled on the upper mounting arm;
• a second cross arm coupled on the lower mounting arm and parallel to the first cross arm;
• and
• carrying arms connecting the first and second cross arms, wherein transceiving antenna modules are mounted on the second cross arm;
• a servomotor configured to drive the first cross arm to rotate along a rotating axis, the servomotor having a first angle sensor for detecting an output rotating angle thereof;
• a second angle sensor, being disposed on a connection where the upper mounting arm and the first cross arm are connected, the second angel sensor being configured to detect an actual rotating angle of the rotary frame, wherein the connection is a position of where the rotating axis is passed through;
• a control component, being electrically connected with the second angle sensor;
• and
• a servo driver, being configured to control the servomotor to rotate according to the actual rotating angle of the frame and the output rotating angle of the servomotor, the first angle sensor and the control component all being electrically connected with the servo driver.
