Abstract
A mixed reality display device includes a waveguide element, an image display device, an imaging lens, a first diffractive optical element, a first volume holographic optical element, a second volume holographic optical element and a second diffractive optical element. The image display device is configured to emit a light field image. The imaging lens is configured to image an image at infinity. The first diffractive optical element is configured to guide the image into the waveguide element. The first volume holographic optical element and the second volume holographic optical element have an angle selectivity, configured to extract a specific field of view. The second volume holographic optical element has a lens array function to form a light field image source. The second diffractive optical element has a lens array function to transfer the light field image source into a three-dimensional image.
