System for detecting and determining trajectories of objects e.g. hand-held weapons, in e.g. airplane, has evaluation unit determining information over trajectory of object, and evaluation unit evaluating image information over trajectory

摘要

The system has a multi-wavelength laser (1) irradiating a detection chamber (13), and a detecting unit detecting radiation reflected from object moved to the chamber. A camera (5) is connected with a diffractive optical unit, and an evaluation unit (9) determines information over a trajectory (10) of the object on the basis of signals detected by the detecting unit. A laser radiation device is formed such that the wavelength radiation time is changed, where the radiation is emitted from the laser. The evaluation unit evaluates camera image information over the trajectory of the object. An independent claim is also included for a method for detecting and determining trajectories of objects moved by a detection chamber.
