Abstract: A system for and method of projecting augmentation imagery in a head-mounted display is disclosed. A system for projecting light onto an eye includes a display to project light, a beam combiner, first and second optical systems between the display and the beam combiner along respective first and second optical paths. The first and second optical paths differ. The system also includes a switchable reflector that, in a reflective state, reflects light incident upon the reflector, and, in a non-reflective state, transmits light incident upon the reflector. The reflector is between the display and the first and second optical systems along the first and second optical paths and directs light along the first path, in the reflective state, or along the second path, in the non-reflective state, to reflect light from the beam combiner to the eye from different directions when in the different states.

Abstract: A tunable acoustic gradient index of refraction (TAG) lens and system are provided that permit, in one aspect, dynamic selection of the lens output, including dynamic focusing and imaging. The system may include a TAG lens and at least one of a source and a detector of electromagnetic radiation. A controller may be provided in electrical communication with the lens and at least one of the source and detector and may be configured to provide a driving signal to control the index of refraction and to provide a synchronizing signal to time at least one of the source and the detector relative to the driving signal. Thus, the controller is able to specify that the source irradiates the lens (or detector detects the lens output) when a desired refractive index distribution is present within the lens, e.g. when a desired lens output is present.
