Abstract:
1. A display system, comprising: a display module including a waveguide holographic display, the waveguide holographic display having a continuously reconfigurable optical characteristic that varies from substantially transmissive for viewing real images to substantially reflective for viewing display images; at least one data capturing device configured to capture data to form a display image; a controller configured to control the optical characteristic of the waveguide holographic display; at least a first projector configured to project the display image to the display module, such that the display image is overlapped with a real image according to an optical configuration of the display, wherein the controller automatically controls the optical characteristic of the waveguide holographic display based on ambient conditions of an external environment and the optical characteristic is substantially transmissive when a power level of the waveguide beam is below a non-zero threshold and is substantially reflective when the power level is above the non-zero threshold.
