Abstract
The disclosed system may include a display; a lens; and a diffractive optical element, where the diffractive optical element includes at least one Pancharatnam-Berry phase grating and is configured to increase a fill factor of the display when the lens is used to magnify the display. Various other apparatuses, systems, and methods are also disclosed.
Claims14
An apparatus comprising a diffractive optical element, wherein the diffractive optical element is configured to increase a fill factor of a display when a lens is used to magnify the display,
- wherein the diffractive optical element comprises at least one Pancharatnam-Berry phase grating,
- wherein the at least one Pancharatnam-Berry phase grating comprises at least one one-dimensional Pancharatnam-Berry phase grating, and
- wherein the at least one one-dimensional Pancharatnam-Berry phase grating comprises:
- a first one-dimensional Pancharatnam-Berry phase grating that diffracts light along a first dimension;
- and
- a second one-dimensional Pancharatnam-Berry phase grating that diffracts light along a second dimension orthogonal to the first dimension.
A system comprising:
- a display;
- a lens;
- and
- a diffractive optical element, wherein the diffractive optical element is configured to increase a fill factor of the display when the lens is used to magnify the display,
- wherein the diffractive optical element comprises at least one Pancharatnam-Berry phase grating,
- wherein the at least one Pancharatnam-Berry phase grating comprises at least one one-dimensional Pancharatnam-Berry phase grating, and
- wherein the at least one one-dimensional Pancharatnam-Berry phase grating comprises:
- a first one-dimensional Pancharatnam-Berry phase grating that diffracts light along a first dimension;
- and
- a second one-dimensional Pancharatnam-Berry phase grating that diffracts light along a second dimension orthogonal to the first dimension.
A method of manufacture comprising:
- positioning a lens to magnify a display;
- and
- positioning a diffractive optical element to increase a fill factor of the display when the lens is used to magnify the display,
- wherein the diffractive optical element comprises at least one Pancharatnam-Berry phase grating,
- wherein the at least one Pancharatnam-Berry phase grating comprises at least one one-dimensional Pancharatnam-Berry phase grating, and
- wherein the at least one one-dimensional Pancharatnam-Berry phase grating comprises:
- a first one-dimensional Pancharatnam-Berry phase grating that diffracts light along a first dimension;
- and
- a second one-dimensional Pancharatnam-Berry phase grating that diffracts light along a second dimension orthogonal to the first dimension.
