Latest Patents

Xuan Wang's latest patents include innovative technologies that push the boundaries of optical display systems. One of his patents is titled "Light field directional backlighting based three-dimensional (3D) pupil steering." This invention describes a head-mounted display device that utilizes light field directional backlighting to achieve three-dimensional pupil steering without mechanical adjustments. The design maintains a compact form factor while delivering high performance. The system comprises two flat components: an array of light sources and an array of modulators, such as a micro lens array and a pinhole array. By digitally modifying the illumination pattern, the light field can be moved in three-dimensional space to correspond with pupil shifts, all while preserving the display content.

Another significant patent is "System and method for measuring satellite ghost efficiency of diffractive lens." This system includes a light source that outputs a probing beam, which is then converted into a non-collimated beam by a beam tweaking assembly. The diffractive lens diffracts this beam into multiple beams, including a first diffracted beam and a second diffracted beam representing a satellite ghost diffraction order. The system is equipped with a detector that generates a beam spot pattern for analysis.
