Abstract
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.
