Modern defense technologies continuously call for new photonic covering, among others, aspects of security and safety. A good example of these is passive laser detection system, widely used to alarm about unfamiliar illumination, potentially indicating danger to human resources and/or advanced equipment. The typical sources illumination are laser rangefinders, illuminators, and beam riders. There is also an obvious tendency observable to use more and more low-power laser systems, which are getting harder to detect. As a result, passive enemy detection techniques are no longer sufficient. That is the reason to add to warning systems also active laser detection of dangerous objects nearby.
This work shows an approach to develop laser system for detection and tracking, which would enable acquisition of characteristic optical signatures and categorizing them as dangerous or not. The main parameters of optical signatures are shape and wavelength, power, pulse length and polarization of the reflected laser beam. The laser system should scan an environment and detect objects, which are considered as potentially dangerous - like camera, telescope, rangefinder lenses. Objects like windows, bottles and car headlights should be categorized as not interesting. Proposed system and practical solution could find place in military as good as in civil sector.
