Abstract
An optical reflective device for reflecting light including a grating medium having a first and second grating structure is disclosed. The first grating structure may be configured to reflect light of a wavelength about a first reflective axis offset from a surface normal of the grating medium at a first incidence angle. The second grating structure may be configured to reflect light of the wavelength about a second reflective axis offset from the surface normal of the grating medium at a second incidence angle different from the first incidence angle. The second reflective axis may be different from the first reflective axis.
Claims20
A device for reflecting light, comprising:
- a grating medium;
- a first grating structure within the grating medium, the first grating structure being configured to reflect light of a wavelength about a first reflective axis offset from a surface normal of the grating medium at a first incidence angle;
- and
- a second grating structure within the grating medium, the second grating structure being configured to reflect light of the wavelength about a second reflective axis offset from the surface normal of the grating medium at a second incidence angle different from the first incidence angle, the second reflective axis being different from the first reflective axis.
A head mounted display device, comprising:
- a light source for providing image-bearing light;
- an optical lens comprising;
- a light input section of the optical lens for receiving the image-bearing light, and;
- a grating medium disposed within the optical lens operatively coupled to the light input section;
- and;
- and
- a pre-distortion manager for applying a blur kernel to a pixel proximal to an edge of a field of view for associated with an image of the image-bearing light.
A method for reflecting light, comprising:
- reflecting, by a first grating structure within a grating medium, at least a first portion of light of a wavelength incident upon the grating medium at a first incidence angle about a first reflective axis offset from a surface normal of the grating medium;
- and
- reflecting, by a second grating structure within the grating medium, at least a second portion of the light of the wavelength incident upon the grating medium at a second incidence angle about a second reflective axis offset from the surface normal of the grating medium, the second incidence angle being different from the first incidence angle and the second reflective axis being different from the first reflective axis.
