Head mounted display apparatus
The occlusion is faithfully expressed even in the binocular vision in the AR display by a head mounted display apparatus or the like. A head mounted display apparatus 10 includes a lens 12, a lens 13, a camera 14, a camera 15, and a control processor 16. A CG image for a right eye is displayed on the lens 12. A CG image for a left eye is displayed on the lens 13. The camera 14 captures an image for the right eye. The camera 15 captures an image for the left eye. The control processor 16 generates the CG image for the right eye in which occlusion at the time of seeing by the right eye is expressed and the CG image for the left eye in which occlusion at the time of seeing by the left eye is expressed, based on the images captured by the cameras 14 and 15 and projects the generated CG image for the right eye and CG image for the left eye onto the lenses 12 and 13. A center of a lens of the camera 14 is provided at the same position as a center of the lens 12. A center of a lens of the camera 15 is provided at the same position as a center of the lens 13.

METHOD FOR RECORDING HOLOGRAPHIC OPTICAL ELEMENT FOR HEAD-UP DISPLAY
Provided is a method in which, when configuring an HUD that produces a holographic image at a distance using a holographic optical element (HOE), an HOE capable of correcting aberrations generated by a projection optical system is manufactured and used to improve the quality of an HUD image. A method for manufacturing an HOE for HUD according to an embodiment of the present invention comprises the steps of: measuring aberrations generated by an optical system that projects an image of a display device; recording the measured aberrations in a master HOE; reproducing an aberrated wavefront of the optical system by playing the master HOE on a display plane on which the image of the display device is expressed; and causing an interference of the reproduced aberrated wavefront and a spherical wavefront irradiated from the HUD image plane on which the image of the display device is created, and recording the interference in the HOE. Accordingly, when configuring the HUD producing an image at a distance using the HOE, the quality of the HUD image can be improved by measuring aberrations in the projection optical system, creating a master HOE that reproduces the measured aberrations, and manufacturing a HOE that corrects the aberrations, and correcting aberrations generated in the projection optical system.
