Abstract
Disclosed are methods and systems for displaying images, and for implementing volumetric user interfaces. One exemplary embodiment provides a system comprising: a light source; an image producing unit, which produces an image upon interaction with light approaching the image producing unit from the light source; an eyepiece; and a mirror, directing light from the image to a surface of the eyepiece, wherein the surface has a shape of a solid of revolution formed by revolving a planar curve at least 180° around an axis of revolution.
Claims20
A system for displaying a hologram to a viewer, the system comprising:
- a hologram generating unit comprising a Spatial Light Modulator (SLM) arranged to produce a holographic image when coherent light is projected thereon and image said holographic image in a volume in space;
- and
- an optical system configured to image said holographic image from said volume in space to form an image at a location in front of a viewer's eye,
- wherein
- when said holographic image is imaged at said location in front of said viewer's eye
- an image of said SLM is imaged at a plane of said viewer's pupil.
A method for displaying a hologram to viewer, the method comprising:
- projecting coherent light onto an SLM;
- imaging a holographic image produced by said projecting said coherent light onto said SLM to a volume in space;
- imaging said holographic image from said volume in space to form an image at a location in front of a viewer's eye,
- wherein
- when said holographic image is imaged from said volume in space to said location in front of said viewer's eye an image of said SLM is imaged at a plane of said viewer's pupil.
A method for displaying a hologram to viewer, the method comprising:
- projecting coherent light onto an SLM;
- imaging a holographic image produced by said projecting said coherent light onto said SLM to a volume in space;
- imaging said holographic image from said volume in space to form an image at a location in front of a viewer's eye,
- wherein
- when said holographic image is imaged from said volume in space to said location in front of said viewer's eye an image of said SLM is imaged at a plane of said viewer's pupil;
- and further comprising:
- tracking a viewer's eye for determining a distance from said volume in space to said plane of said viewer's pupil;
- and
- adjusting an optical-length adjusting element, thereby imaging said SLM at a distance of said plane of said viewer's pupil.
