Embodiment 1
[0051]In Embodiment 1 of the present invention, a personnel safety inspection system 100 is provided, including: a channel 110, the channel 110 provides an inspection space isolated or partially isolated from the surrounding environment, and at least one The sub-channels are for the inspected person 102 to pass through, and at least one millimeter-wave imaging device 120 is provided for each of the sub-channels to perform millimeter-wave imaging on the inspected person 102; and an ion mobility spectrometer 130 is used to image the inspected person The particle or gas emitted or volatilized by the inspector 102 into the air in the channel 110 is ionized, and then its migration rate under the action of an electric field is measured to identify the substance.
[0052] The personnel security inspection system 100 also includes a console 150 for controlling the work of at least one millimeter-wave imaging device 120 and the ion mobility spectrometer 130 , and receiving data from the...
Embodiment 2
[0070] On the basis of Embodiment 1, another millimeter-wave imaging device (not shown in the figure) is installed on both sides of the subject to monitor and measure both sides of the subject.
Embodiment 3
[0072] Similar to Embodiment 1, but the millimeter wave imaging device 120 is modified into four millimeter wave imaging devices. If the moving direction A of the person is taken as the x direction, and the midpoint of the measurement line or the midpoint of the measurement region (ie the center point of the region) 117 is taken as the origin, a coordinate system is established on the ground plane. Then, a millimeter-wave imaging device 120 is respectively installed in directions of about 45 degrees, 135 degrees, 225 degrees, and 315 degrees, and its aperture faces are all facing the vertical line passing through the origin of coordinates, and its top view is as follows figure 2 shown. The feature of Embodiment 3 is that the millimeter wave imaging device 120 inspects the inspected person from four angles of view, the millimeter wave imaging device 120 can be placed upright, and the person can go straight without resistance.
