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.
Claims44
A method of floating-in-the-air image display, comprising:
- providing a floating-in-the-air display device at a location;
- and
- projecting from said device one or more floating-in-the-air computer generated images, viewable over a range of angles including at least 200 arc degrees surrounding said location.
A hologram display device projecting a floating in the air computer generated hologram simultaneously viewable over a range of viewing angles of at least 180 degrees.
A method of displaying content to multiple viewers, the method comprising:
- forming multiple volumetric images, each of at least a portion of the content and each viewable from its own viewability space;
- and
- overlapping a portion of one or more of said viewability spaces with a pupil of each of the viewers.
A method of displaying a scene to a viewer looking towards a given location, the method comprising:
- estimating the position of the viewer's eye;
- estimating which scene-portions the viewer would have seen if the scene was at the given location in a given orientation;
- and
- imaging to the given location a computer generated hologram of only a portion of the scene, said portion comprising said estimated scene-portions, wherein imaging is such that the viewer can see the hologram.
A system for imaging a computer-generated hologram (CGH), the system comprising:
- a hologram generating unit comprising a spatial light modulator (SLM);
- an optical system configured to image a hologram generated by said unit to a first location and an image of the SLM to a second location;
- and
- a controller configured to control the imaging of said image of the SLM to the second location, such that the CGH is imaged to a location between the optical system and the image of the SLM.
A system for displaying content to multiple viewers, the system comprising
- a unit for generating volumetric images each of at least a portion of the content and each viewable from its own viewability space;
- and
- an optical system, controlling a portion of one or more of said viewability spaces with a pupil of each of the viewers.
A system comprising:
- an image producing unit, producing a paraxial image;
- and
- an optical system defining a stage and imaging said paraxial image to said stage, such that the image on the stage is viewable from a viewability space,
- wherein said optical system comprises an eyepiece and a mirror, the mirror being configured to direct light to the eyepiece in a plurality of different azimuthal angles, and wherein
- each of said azimuthal angles determines a different location for said viewability space;
- and
- for each of said azimuthal angles the location of the stage is the same.
A method of imaging a paraxial image to be seen by a viewer having a pupil in a first location and looking at a second location, the method comprising:
- generating the paraxial image;
- imaging the paraxial image to the location at which the viewer looks, such that an image of the paraxial image is viewable from a viewability space having a broadest portion and narrower portions;
- selecting, responsive to the location of the viewer's pupil, a third location;
- and
- imaging the broadest portion of the viewability space to the selected third location.
