摘要:
The present invention discloses a millimeter-wave inspection apparatus. The millimeter-wave inspection apparatus comprises: optics devices (30, 40, 50), configured to receive millimeter-wave energy radiated from an object to be inspected and focus the received millimeter-wave energy; a radiometer receiving device(80) 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.

Disclosed is a scanning device using radiation beam for backscatter imaging. The scanning device includes a radiation source; a stationary shield plate and a rotary shield body positioned respectively between the radiation source and the subject to be scanned, wherein the stationary shield plate is fixed relative to the radiation source, and the rotary shield body is rotatable relative to the stationary shield plate. The ray passing area permitting the rays from the radiation source to pass through the stationary shield plate is provided on the stationary shield plate, and ray incidence area and ray exit area are respectively provided on the rotary shield body. During the process of the rotating and scanning of the rotary shield body, the ray passing area of the stationary shield plate intersects consecutively with the ray incidence area and the ray exit area of the rotary shield body to form scanning collimation holes. Further, a scanning method using radiation beam for backscatter imaging is also provided.
