Title:
NON-CONTACT TYPE BAGGAGE DETECTOR
Document Type and Number:
Japanese Patent JP2004177131
Kind Code:
A
Abstract:
To provide a small-sized non-contact type chemical substance detector capable of detecting a chemical substance packed or filled in a package or a container, without opening it, and capable of detecting the chemical substance simultaneously.
This detector emits 0.1-10 MHz of radio wave to detect an NQR of an atom contained in the chemical substance using a high-temperature superconductive SQUID magnetic sensor highly sensitive to a low-frequency wave. A substance is identified by collation with known spectra of an explosive, a poison, a narcotic and the like. A substance not captured by a metal finder in hand baggage inspection and custom office inspection or the like in an airport is captured with high sensitivity.
