Abstract
A fiber bundle head up display includes a bundle of optical fibers. An image source projects a display image onto the fiber bundle. The fiber bundle transfers the display image from its input surface to its output surface and projects the display image onto a combiner, which superimposes the display image in the visual field of a viewer. The fiber bundle transforms the display image while performing three-dimensional relocation of picture elements of the display image to reduce aberration and distortion of the display image. The fiber bundle may be utilized for pre-transforming the display image to reduce or eliminate a variety of image aberration types.
Claims15
A head up display comprising:
- an image source configured to project a display image including one or more picture elements;
- a plurality of optical fibers having an input surface and an output surface and including a first optical fiber that changes position relative to a second fiber and a third fiber between the input surface and the output surface, wherein a change in a relative position of a first optical fiber and a second optical fiber between the input surface and the output surface is non-proportional with respect to a change in relative position of the first optical fiber and a third optical fiber between the input surface and the output;
- and
- a combiner positioned to receive the display image from the output surface.
A method for superimposing a display image in a visual field, comprising:
- receiving the one or more picture elements with a plurality of optic fibers having an input surface and an output surface;
- transmitting one or more picture elements from the input surface to the output surface, wherein a first picture element changes position relative to a second picture element and a third picture element between the input surface and the output surface, wherein a change in a relative position of a first picture element and a second picture element between the input surface and the output surface is non-proportional with respect to a change in relative position of the first picture element and a third picture element between the input surface and the output surface;
- and
- projecting a display image from the output surface of the plurality of optical fibers to a combiner positioned to receive the display image.
A system for superimposing a display image in a visual field, comprising:
- means for projecting a display image including one or more picture elements;
- a plurality of optical fibers having an input surface and an output surface and including a first optical fiber that changes position relative to at least one of a second fiber and a third fiber between the input surface and the output surface, wherein a change in a relative position of a first optical fiber and a second optical fiber between the input surface and the output surface is non-proportional with respect to a change in relative position of the first optical fiber and a third optical fiber between the input surface and the output surface;
- means for receiving the display image from the output surface.
A head up display for superimposing a display image in a visual field, comprising:
- an image source configured to project a display image including one or more picture elements;
- a plurality of optical fibers having an input surface and an output surface and including a first optical fiber that changes position relative to at least one of a second fiber and a third fiber between the input surface and the output surface, wherein a change in a relative position of a first optical fiber and a second optical fiber between the input surface and the output surface is non-proportional with respect to a change in relative position of the first optical fiber and a third optical fiber between the input surface and the output surface;
- a combiner positioned to receive the display image directly from the output;
- and
- a user-wearable mount for supporting the plurality of optical fibers, the image source, and the combiner.
