Abstract
The present disclosure relates to a non-contact type security inspection and method, the system including: a laser source for emitting probe light beams which penetrate through a container or a packaging and are irradiated onto an inspected object contained in the container or the packaging; an optical collection device for collecting an exciting light excited by the probe light beams on the inspected object; a spectrum analyzer for analyzing spectral characteristics of the exciting light collected by the optical collection device so as to determine characteristics of the inspected object; and a shielding apparatus for preventing at least part of the exciting light excited by the probe light beams on the container or the packaging from entering an induction area of the optical collection device.
