Abstract
A polarizing beamsplitter (PBS) that can be used with reflective light valve displays includes two polarizing surfaces. A light source projects opposing readout beams onto the polarizing surfaces, which reflect linearly polarized (S or P) components of the readout beams. The polarized readout beams illuminate respective portions of a reflective light valve cell that bears an image intensity pattern. The cell spatially modulates the readout beams' polarization in accordance with the image intensity pattern and reflects the polarization modulated beam back towards the polarizing beamsplitter. The PBS spatially analyzes the readout beams' intensities in accordance with their polarization modulations.
