Abstract
Described examples include a projection system having projection optics with a projection optics axis tilted from an axis perpendicular to an image target, the projection optics configured to project an image. The projection system also having an image source, the image source configured to provide the image, the image source having an offset from the projection optics axis, a plane of the image source having an angle from perpendicular to the projection optics axis such that a projected image from the image source projected by the projection optics is focused onto the image target along an extent of the projected image.
Claims20
A projection system comprising:
- projection optics having a projection optics axis tilted from an axis perpendicular to an image target, the projection optics configured to project an image;
- and
- an image source configured to provide the image, the image source having an offset from the projection optics axis, a plane of the image source having an angle from perpendicular to the projection optics axis such that a projected image from the image source projected by the projection optics is focused onto the image target along an extent of the projected image.
A projection system comprising:
- projection optics having a projection optics axis tilted from an axis perpendicular to an image target, the projection optics configured to project an image;
- and
- a spatial light modulator configured to provide the image, the spatial light modulator having an offset from the projection optics axis, a plane of the spatial light modulator having an angle from perpendicular to the projection optics axis such that a projected image from the spatial light modulator projected by the projection optics is focused onto the image target along an extent of the projected image, wherein the image is adjusted to provide a corrected projected image.
A method comprising:
- providing an image using an image source;
- and
- projecting the image using projection optics, wherein the projection optics has a projection optics axis that is at a first angle from perpendicular to an image target, and wherein the image source is offset from the projection optics axis.
