Polaritonic meta-material combat identification

摘要

An identification apparatus, capable of distinguishing between a first class of objects and a second class of objects. This identification apparatus includes an identification tag, which is capable of providing a certain reflection band and a certain thermal emission band. The identification apparatus also includes a thermal weapon sight which has a long-wave infrared band-pass filter. This band-pass filter passes through a desired range of wavelengths and filters out an undesired range of wavelengths. The reflection band and the thermal emission band are detectable within the desired range of wavelengths.

1. An identification apparatus, capable of distinguishing between a first class of objects and a second class of objects, said identification apparatus comprising:
an identification tag, said tag being capable of emitting a desired reflection band signal and a desired thermal emission band signal upon receiving an interrogation beam, wherein a respective said identification tag is attached to each object of said first class of objects and is not attached to objects of said second class of objects; and a thermal weapon sight for sending the interrogation beam, said thermal weapon sight having a long-wave infrared band-pass filter, wherein said band-pass filter passing a desired range of wavelengths and filtering out an undesired range of wavelengths, wherein said desired reflection band signal and said desired thermal emission band signal emitted by the identification tag attached to said first class of objects are within the desired range of wavelengths and passed by said band-pass filter, thereby distinguishing between the objects of the first class of objects and the objects of the second class of objects.
