Title:
SECURITY CHECK SYSTEM AND METHOD BY MEANS OF THREE-DIMENSIONAL HOLOGRAPHIC IMAGING
Document Type and Number:
WIPO Patent Application WO/2017/185553
Kind Code:
A1
Abstract:
A security check system and method by means of three-dimensional holographic imaging. The system comprises: a body frame (1); a millimeter wave transceiver module (2) provided on the body frame (1); at least two sets of millimeter wave switch antenna arrays (6, 7) connected to the millimeter wave transceiver module (2), the number of millimeter wave switch antenna arrays (6, 7) being equal to the number of scanning areas (8, 9); a scanning driving means (5) for driving the at least two sets of millimeter wave switch antenna arrays (6, 7) to rotate in the same direction; a control means (3) for controlling the scanning driving means (5) to generate a rotation angle signal; an image parallel processing module (4) for obtaining, by synthesis, the three-dimensional holographic image of a detected object according to an echo signal collected by the millimeter wave transceiver module (2) and spatial location information corresponding to the echo signal. The system has a simplified structure and a high resulting imaging resolution.
