Abstract
An apparatus and method for increasing resolution and expanding the displayed field of view. The imagery is collimated and split into two paths by a partially reflective mirror set at an oblique angle to the image source. Either path may be blocked by a combination of polarizers and at least one controllable polarization shifting cell(s) (.pi.-cells). This mechanism allows one image source to supply, in alternating sequence, separate imagery to two separate but contiguous portions of a wide angle display. The two collimated image paths are merged about the viewing axis by a one way mirror before being recollimated at the device exit pupil.
