    Abstract: A system for projecting dots onto a three-dimensional image is configured to activate multiple pseudo-random dot projectors sequentially. Each pseudo-random dot projector includes an illumination source and a wavefront modulating element (WME) located along an optical axis in a path traversed by radiation produced by the illumination source. The system is configured to form images of dots in the projection plane along the optical axis. The system may also include controlling circuitry configured to perform a sequential projection operation on the plurality of pseudo-random dot projection systems to produce a temporal sequence of images and aggregate and process the temporal sequence of images to produce a high-resolution depth image of the three-dimensional surface.

    Abstract: An autostereoscopic display system includes a transmissive display panel including a backlight having an array of backlight pixels, a selectively-selectively-transmissive display pixel matrix having a first side facing the backlight and an opposing second side, the selectively-transmissive display pixel matrix comprising an array of display pixels, a first lenticular array disposed between the backlight and the first side of the selectively-transmissive display pixel matrix, and a second lenticular array disposed facing the second side of the selectively-transmissive display pixel matrix. The backlight is configured to separately activate different subsets of the backlight pixels such that light emitted from an activated subset of backlight pixels and transmitted through the first lenticular array, the selectively-transmissive display pixel matrix, and the second lenticular array is emitted by the display panel as display light in a corresponding separate direction relative to the display panel.

    Abstract: A computer workstation includes a curved autostereoscopic display having one or more display regions. The workstation further includes one or more image capturing devices to capture images (e.g., two-dimensional images and depth information) of a user of the workstation, and also includes an eye-tracking module to track the positions of the user's eyes as she uses the workstation. Based on the captured imagery, the workstation generates a 3D model of the user for communication to other remote workstations via a network. The workstation receives 3D models of the users of the remote workstations via the network. Based on the received 3D models and the detected eye positions of the user, the workstation generates frames for display at the curved autostereoscopic display.
