Polarization Compensation for Corner Cube Reflector
Existing corner cube reflectors introduce unwanted polarization change to incident light. This invention provides a solution to remove this polarization change and thereby reduces polarization dependent loss and improves the performance of the reflector. This solution can be applied to both mirror-based and prism-based corner cube reflectors. This invention...
