Abstract
Embodiments described herein include an augmented reality (AR) optical system, and associated method and computer program product, defining a field of view relative to an optical reference point. The optical system comprises an imagery display configured to display images using a received first display signal, and a beam-splitter disposed within the field of view and configured to cause the displayed images to appear in a first focal plane within the field of view. The optical system further comprises an occluding display disposed within the field of view and configured to display, based on the first display signal, occluding images in a second focal plane nearer to the beam-splitter than the first focal plane, thereby reducing environmental light at the optical reference point for at least a portion of the displayed images.
