Abstract

See full text

A method is provided that transmits a beam of co-propagating, cross-polarized light to a target. The method receives return light reflected from the target, which includes a first polarization and a second polarization. The method splits the return light into a first output corresponding to the first polarization and a second output corresponding to the second polarization using a first beam splitter. The method directs the first output to a first detector and directs the second output to a second detector. The method generates, by the first detector, a first electrical signal corresponding to the first polarization, and generates, by the second detector, a second electrical signal corresponding to the second polarization. The method determines an orientation of the target based on the first electrical signal and the second electrical signal, and generates a point cloud based on the orientation of the target.
