摘要： The present disclosure provides a security inspection apparatus and a method of controlling the same. The security inspection apparatus includes: a bottom plate configured to carry an inspected object; and a two-dimensional multi-input multi-output array panel, including at least one two-dimensional multi-input multi-output sub-array. Each two-dimensional multi-input multi-output sub-array includes a plurality of transmitting antennas and a plurality of receiving antennas, and the plurality of transmitting antennas and the plurality of transmitting antennas are arranged such that equivalent phase centers are arranged in a two-dimensional array. The security inspection apparatus further includes: a control circuit configured to control the plurality of transmitting antennas to transmit a detection signal in a form of an electromagnetic wave to the inspected object in a preset order, and to control the plurality of receiving antennas to receive an echo signal from the inspected object; a signal processing device configured to reconstruct an image of an inspected object based on an echo signal received; and a display device configured to display the reconstructed image of the inspected object.

摘要： A converged system and method for a radiation imaging and a radioactive material monitoring of a luggage or package object (105, 205, 305) are provided. The converged system includes: a radiation imaging subsystem (10) configured to operate in a pulse mode to perform a radiation imaging on the luggage or package object (105, 205, 305); a radioactive material monitoring subsystem (20) configured to operate in the pulse mode to monitor whether the luggage or package object (105, 205, 305) contains a radioactive material; and a synchronization control subsystem (30) being in communication with both the radiation imaging subsystem (10) and the radioactive material monitoring subsystem (20), and configured to control the radiation imaging subsystem (10) and the radioactive material monitoring subsystem (20) to operate alternately.
