Publication number: 20190113829Abstract: Systems integrating display resolution-multiplication solutions can be implemented in a variety of different ways. In many embodiments, the system includes an image projector for projecting image light, an image processor for computing a native image and at least one image shifted in a predefined direction, and at least one switchable grating capable of being switched between diffracting and non-diffracting states. In some embodiments, the switchable grating is optically coupled to the image projector. In a number of embodiments, the switchable gratings have a first configuration for propagating the native image light and at least one other configuration for propagating shifted image light having an angular displacement corresponding to the image shift in a predefined direction. By displaying the native and shifted images sequentially within a human eye integration period, the display resolution can be multiplied.Type: ApplicationFiled: October 16, 2018Publication date: April 18, 2019Applicant: DigiLens, Inc.Inventors: Jonathan David Waldern, Alastair John Grant, Milan Momcilo Popovich
