Abstract
An unpolarized light beam is split into two orthogonal polarized beams. Each polarized beam is attenuated by passing it through the sequence of a first polarization rotator, an analyzer, and a second polarization rotator. The attenuated beams are combined to yield a beam with the desired type or space-orientation of polarization.
