Abstract
The present invention discloses a millimeter-wave inspection apparatus. The millimeter-wave inspection apparatus comprises: optics devices, configured to receive millimeter-wave energy radiated from an object to be inspected and focus the received millimeter-wave energy; a radiometer receiving device configured to receive the focused millimeter-wave energy and transform the millimeter-wave energy into electrical signal; and an imaging device configured to generate a temperature image of the object to be inspected based on the electrical signal. Compared with the prior art, the millimeter-wave inspection apparatus of the present invention has a simple and compact structure; it would not be harmful to the human health by employing the passive millimeter-wave human body security inspection technology. With the above configuration, the contraband items to be concealed within the human clothing can be efficiently and effectively detected.
