Abstract
In accordance with yet another aspect of the present invention, an active imaging system is provided for imaging a target of interest. An imaging assembly includes a light source and an optical assembly comprising a plurality of passive optical components. The optical assembly divides received light into a first beam, having a first polarization and a second beam, having a second, orthogonal polarization, directs the first and second beam along respective first and second optical paths within the optical assembly, and recombines the first and second beams into a combined beam. A sensor detects the combined beam.
