摘要:
The present application relates to a method, apparatus and system for inspecting an object based on a cosmic ray, pertaining to the technical field of radiometric imaging and safety inspection. The method includes: recording (S110) a movement trajectory of an inspected object by using a monitoring device; acquiring (S120) information of charged particles in the cosmic ray by using a position-sensitive detector, the information of charged particles comprising trajectory information of the charged particles; performing (S130) position coincidence for the movement trajectory and the trajectory information to determine the object; performing (140) trajectory remodeling for the charged particles according to the information of charged particles; and identifying (S150) a material inside the moving object according to the trajectory remodeling. According to the present disclosure, pedestrians who are walking and moving are inspected by using the cosmic ray, and nuclear materials, drugs and explosive materials and the like carried by human bodies may be detected.
摘要:
The present invention discloses a gas analyzing apparatus and a sampling device. The gas analyzing apparatus includes a sampling device and an ion mobility spectrum analysis device. The sampling device includes a multi-capillary column and a temperature controlling system. The ion mobility spectrum analysis device is adapted for analyzing a gas leaded-in by the sampling device and includes a reaction cavity for reaction between sample molecules and reaction ions, the cavity having a sampling opening for leading-in of the gas. An outlet end of the multi-capillary column is inserted directly into the cavity of the ion mobility spectrum analysis device through the sampling opening of the ion mobility spectrum analysis device.
