Abstract

A device can determine a distance to an object. The device can use the determined distance to vary a focal length of a first adjustable element so that the first adjustable element directs light from the object into a first waveguide and onto a detector, and forms an image of the object at the detector. The device can produce an image, such as augmented content, on a panel. The device can direct light from the panel into a second waveguide. The device can use the determined distance to vary a focal length of a second adjustable element so that the second adjustable element directs light out of the second waveguide and forms a virtual image of the panel in a plane coincident with the object. The device can operate as an augmented reality headset. The adjustable elements can be phase modulators, or acoustically responsive material with surface acoustic wave transducers.
