MILLIMETRE WAVE THREE DIMENSIONAL HOLOGRAPHIC SCAN IMAGING APPARATUS AND METHOD FOR INSPECTING A HUMAN BODY OR AN ARTICLE

摘要

The present invention discloses a millimetre wave three dimensional holographic scan imaging apparatus and a method for inspecting a human body or an article. The apparatus comprises a first millimetre wave transceiver module, a second millimetre wave transceiver module, a first guide rail device to which the first millimetre wave transceiver module is connected in slidable form, a second guide rail device to which the second millimetre wave transceiver module is connected in slidable form, a driver configured to drive the first/second millimetre wave transceiver module to move along the first/second guide rail device, and a constrainer configured to constrain kinematic relation between the first and the second millimetre wave transceiver modules such that they only move in directions opposed to each other. They may increase scan speeds, improve scan stability, reduce scan operations and enhance the reliability of the apparatus.

1. A millimetre wave three dimensional holographic scan imaging apparatus, comprising:
a first millimetre wave transceiver module comprising a first millimetre wave transceiver antenna array for transmitting and receiving a first millimetre wave signal; a second millimetre wave transceiver module comprising a second millimetre wave transceiver antenna array for transmitting and receiving a second millimetre wave signal; a first guide rail device, to which the first millimetre wave transceiver module is connected in slidable form, such that the first millimetre wave transceiver module is moveable along the first guide rail device to perform a first scan on an object to be inspected; a second guide rail device, to which the second millimetre wave transceiver module is connected in slidable form, such that the second millimetre wave transceiver module is moveable along the second guide rail device to perform a second scan on the object to be inspected; a driver configured to drive the first millimetre wave transceiver module to move along the first guide rail device and/or to drive the second millimetre wave transceiver module to move along the second guide rail device; and a constrainer configured to constrain kinematic relation between the first millimetre wave transceiver module and the second millimetre wave transceiver module such that the first millimetre wave transceiver module and the second millimetre wave transceiver module only move in directions opposed to each other.
