摘要： A system including an optical path length extender (OPLE) having two light paths having different path lengths, such that light entering the OPLE with a first polarization is directed through a first light path, and light entering the OPLE with a second polarization is directed through a second light path through the OPLE. The OPLE includes a first polarization sensitive reflective element at a first angle to the light entering the OPLE and a second angled polarization sensitive reflective element at a second angle to the light entering the OPLE, the second angled polarization sensitive reflective element intersecting the first polarization sensitive reflective element.

摘要： A system including a rendering engine to render a field texture for a field display and a foveal texture for a steerable foveal display and a compositor including a field compositor to generate frames for the field display from the field texture and a foveal compositor to generate frames for the foveal display from the foveal texture. The system further including a composition manager designed to sequence and select what is presented including one or more of data in the field display and the foveal display.

摘要： A system to adjust light path length comprising a digital light path length modulator, the digital light path length modulator comprising a polarization modulator to receive polarized light and to modulate a polarization of some or all of the polarized light. The system further comprising an optical path length extender (OPLE) having an entry surface and an exit surface, to direct the light entering the OPLE with a first polarization through the entry surface and along a first light path through the OPLE to exit through the exit surface, and to direct the light entering the OPLE with a second polarization through the entry surface and along a second light path through the OPLE to exit through the exit surface, the second light path through the OPLE having a light path length two or more times longer than the first light path length through the OPLE.

摘要： A relative position based eye tracking system includes a light source to illuminate a portion of the eye and an optical sensor to capture a sequence of samples of the portion of the eye. The system further includes a sample comparator to compare two samples and a relative position calculator to calculate a change in the position of the eye based on data from the sample comparator.

摘要： A system including a steerable mirror, a waveguide, first optics, intermediate optics, and final optics. The system includes a first light path for a foveal image element, the first light path including the first optics, the steerable mirror to steer a position of the foveal image element to a particular orientation, intermediate optics, and the final optics to direct the foveal image element to an in-coupling region of the waveguide. The system further includes a second light path for a field image element, the second light path including final optics.
