Abstract
A personal video viewing device is provided which allows the simultaneous viewing of a stereoscopic external image as well as a monoscopic electronic image. This is accomplished using two optical systems which share particular components. The relative intensity of both images may be adjusted using a three-iris system where each iris may be a mechanical diaphragm, an electronically controlled liquid crystal device, or a pair of polarized discs whose relative rotational orientation controls the transmissivity of the disc pair.
