Abstract: A stereoscopic display device is provided for displaying a three-dimensional (3D) image as viewed by eyes consisting of a left eye and a right eye. In the display device, a single display screen, or separate left and right display screens, present a left image to the left eye but not the right eye, and present a right image to the right eye but not the left eye. A gaze distance tracker is configured to track gaze distance of the eyes. Variable-power lenses include a left variable-power lens arranged to provide eye accommodation for the left eye, and a right variable-power lens arranged to provide eye accommodation for the right eye. An electronic eye accommodation controller is configured to control the power of the variable power lenses to allow the image from the display to be focused on the retina, while the biological eye lens is accommodated to the gaze distance.

Abstract: An optical phased array transmitter/receiver includes a plurality of waveguides each including an optical fiber and a light source coupled to the fibers in the waveguides. At least one grating is coupled to the fiber of each waveguide and at least one phase shifter coupled to the fiber of at least one waveguide. The phase shifter controls a phase profile of light passing through the fiber to control a profile of a laser beam reflected at the grating. The gratings reflect light passing through the fibers outside of the optical coder to form a laser beam shaped and directed by the grating and phase shifters. Further, a detector is coupled to the waveguides that is enabled to receive light reflected off the gratings. Other embodiments are described and claimed.
