THz identification of humans and concealed weapons for law enforcement, government, and commercial applications

摘要

Described is the principal of THz sensing and its implementation based on a newly discovered possibility in a sub visible range to penetrate through various materials and to be absorbed by them to a various extent. The advantage of the proposed solution stems from a greater degree of mobility of the sensor and its ability to distinguish between different materials - the feature not attainable by the X-Ray apparatus. The identification may be also more "diplomatic" since it does not involve "seeing through". Presented is the description of the identification devices as well as the results of the measurements of the object of interest, and the prospects of a further development of the proposed principle/device.
