Abstract: The present disclosure describes optical elements and optical devices that use the optical elements to allow the output of two imagers to be combined onto a single optical axis. Each of the two imagers can be based on alternate polarization directions, and the disclosed embodiments can enable high contrast 3D projectors without requiring either time or polarization sequencing. The present disclosure further describes projection systems that include the optical devices.
