Abstract
An optical assembly for a digital projector includes a lens and a field bias optical element. The lens is disposed to receive display light generated by a display and to direct the display light along an optical path. The lens is configured to provide a first field-of-view. The field bias optical element is disposed between the lens and an aperture stop of the optical assembly. The field bias optical element is configured to bias the display light in at least one direction to provide a second field-of-view that is greater than the first field-of-view.
