Claim One:
1. An optomechanical switching device for a photopolarimetric lidar standoff detection system comprising a plurality of laser beams and a plurality of spectrum analyzers, the optomechanical switching device comprising: a platform for mounting optical elements; a translation stage mounted to the platform and selectively translatable along a first axis; a first mirror mounted on the translation stage and oriented at a predetermined angle to reflect a first laser beam along a second axis substantially orthogonal to the first axis; a second mirror mounted on the translation stage orthogonally to the first minor and oriented at a predetermined angle to reflect a second laser beam along a second axis; a third mirror selectively positionable in and out of the path of the second laser beam to deflect the second laser beam to a beam terminator; a fourth mirror selectively positionable in and out of the path of the first laser beam to deflect the first laser beam to a beam terminator; a fifth mirror fixed in position and oriented at a predetermined angle to reflect the laser beam from the first mirror to a first spectrum analyzer; a sixth mirror fixed in position and oriented at a predetermined angle to reflect the laser beam from the second mirror to a second spectrum analyzer; a seventh mirror selectively positionable in and out of the path of the laser beams thereby deflecting the beams to a beam terminator; a polarizer in the path of the second axis; and; a phase shifting element in the path of the second axis.
