A system and method includes a laser transmitter configured to form a transmitted laser beam and a laser receiver configured to receive a reflected beam based on the transmitted laser beam. An identification (ID)-filter includes a substrate, a retarder filter and a reflector, where the transmitted beam passes through the retarder filter and is reflected back through the retarder filter in an opposite direction, to the laser receiver. A processor connected with a memory executes instructions stored in the memory to determine polarization properties of the reflected beam with respect to the transmitted laser beam to determine an address of the ID-filter.

System and method for non-contact identification of a passive target

There is provided a method for detecting a target material, preferably a solid or liquid target material. The method may comprise the steps of targeting a material for analysis, heating the material with a heating source from a remote distance to effectively increase a temperature of the material and to effectively increase a vapor pressure of the material in an environment adjacent to the material, measuring with a sensor the material vapor in the adjacent environment from the remote distance, and detecting the identity of the material using data generated during the measuring step. There is also provided a system for detecting a target material having a low vapor pressure comprising a first energy generating source, a sensor for measuring properties of gaseous materials from a standoff distance, the sensor producing data, and a computer for determining the target material based on the data produced by the sensor.
