Polarized Beam Director and Method

摘要

Incident differently-polarized light beams are separately directed and combined by one or two corner cube structures, each having one or two walls formed as a beam splitter. One incident light beam is passed, while the other incident light beam is reflected.

主权项

1. A polarized beam director for separately directing first and second incident light beams having respectively different planes of polarization, comprising:
a corner cube structure comprising first, second and third walls occupying a mutually perpendicular relationship with respect to one another and intersecting at one of an actual or virtual corner, the first and second incident light beams impinging upon at least one of the first, second and third walls; and wherein: the first wall comprises a beam splitter; the beam splitter of the first wall has polarization characteristics which pass the first incident light beam and reflect the second incident light beam; and the first, second and third walls reflect the second incident light beam.
