  • Patent number: 11656466
    Abstract: A display method and system includes a module that intercepts the lightfield from an ambient Real World Scene in an observer's direct line-of-sight, 102, and then routes it through a spatial light modulator where the Scene forms an image. During a first portion of the frame time, selective pixels corresponding to the real world scene image on the SLM are modulated for their transparency or opacity and routed to the observer's eye. In a second portion of the frame time, a Digital computer generated Virtual image is created by spatially multiplexing a second illuminant on the same SLM and then routing it to the observer's eye. The resultant time-averaged image, as perceived by the observer, has the Real World Scene modulated for both its Transparency/opacity and also blended with computer generated Digital Virtual image.
