摘要： A polarization switching apparatus has a first birefringent polarizer formed as a composite prism and disposed to direct incident light of a first polarization along a first optical path and light of a second polarization along a second optical path, wherein the second optical path is oblique to the first optical path. A beam redirector is disposed to redirect the first optical path from the first birefringent polarizer toward an input face of a second birefringent polarizer; wherein the second birefringent polarizer is also formed as a composite prism and is disposed to combine incident light of the first and second polarizations onto a common output path. A shutter apparatus is actuable to selectively block light of the first polarization or light of the second polarization from the input face of the second birefringent polarizer.
