  • Patent number: 10371625
    Abstract: Identification of reflective surfaces as being associated with optical threats is disclosed. A first laser signal is emitted from a first laser system at a first wavelength and a first emission circular polarization orientation. A first signal reflection of the first laser signal from a reflective surface at the first wavelength having a first return circular polarization orientation that is different from the first emission circular polarization orientation is detected. A first return quantification of the first signal reflection, based at least in part on an amount of circular polarization of the first signal reflection, is determined. It is determined that the reflective surface is associated with a threat optic based at least in part on the first return quantification.
