Security inspection system and method using the three-dimensional holographic imaging technology

A security inspection system using the three-dimensional (3D) holographic imaging technology, comprising a body frame (1) having a to-be-scanned area (10) and at least two scan areas formed therein, the security system further comprising:

• a millimeter-wave transceiving module (2), at least two millimeter-wave switch antenna arrays, a scan driving device (5) and a parallel-image processing module (4);
• the number of the millimeter-wave switch antenna arrays being the same as the number of the scan areas;
• each of the millimeter-wave switch antenna arrays being connected to the millimeter-wave transceiving module (2) respectively;
• the scan driving device (5) being disposed on the body frame (1) and configured to drive the at least two millimeter-wave switch antenna arrays to rotate along a same direction, so that each of the millimeter-wave switch antenna array performs a rotary-scanning operation for an under-test object in the to-be-scanned area (10) within a corresponding scan area respectively;
• the parallel-image processing module (4) being configured to synthesize a three-dimensional (3D) holographic image of the under-test object according to echo signals collected by the millimeter-wave transceiving module (2) and spatial position information of the echo signals.
