Polarization measurements can be used to distinguish different objects. In this work, polarimetry has
been used as a useful tool to differentiate between two geometries, viz., a cube and a cylinder, demonstrating
that polarization “signatures” can be obtained from the reflection of passive lighting. A novel approach to
characterizing geometries using vector-vector space has been demonstrated to be effective in differentiating
between these two geometries and lends itself well to a statistical analysis that is applicable for computer
generated target identification.
