FIELD: use of nuclear quadrupole resonance (NQR), in particular, safety systems at inspection of access to guarded rooms. ^ SUBSTANCE: the NQR detector has an intake, signal normalization and processing unit, N video cameras, optical information processing device, weight platform, weigher, NQR transducer and indicator, transmitting device, damping device and an NQR transducer circuit tuning device. The person undergoing the inspection is placed in a double-glazed cabin and located on the weight platform positioned inside the cabin, whose inner wall is made of dielectric, and the outer wall serves as a screen. The NQR transducer circuit is positioned between the cabin walls, N video cameras are so installed that they do not detect the person undergoing the inspection in the preset position. ^ EFFECT: provided detection of metals, explosives, caseless inclusive, and narcotics, as well as their identification. ^ 2 cl, 6 dwg |
