Optical Design of Waveguide Holographic Binocular Display for Machine Vision

Abstract:

A binocular display can satisfy competition mechanism of biological vision system and improve display precision. A binocular optical system is designed with waveguide holography (WGH) for small size and light weight. A superimposed holographic volume grating can split the image bearing lights into two equal intensity light beams. The out-coupling waveguide holographic gratings for the left and right eyes can implement image extension and imaging display. The simulation and experimental results reveal that excellent optical performances can be achieved for little distortion of less than 0.05%(nearly zero), light weight of about only 32g, and compact size. The display information can also be overlaid the outside scenes in eyeglass augmented reality and Machine Vision Display applications.
