Abstract
Systems and methods of virtual displays integrated into medical and other environments, in particular in medical diagnostic tools or medical imaging tools. In some embodiments, the viewer is close to an exit aperture of the display system. In some embodiments, components and subsystems of the apparatus are non-magnetic and compatible with MRI in-bore applications. In some embodiments, the light source is physically distant or exterior from the optical subsystem producing a virtual image. In some embodiments, the virtual image has monocular depth or stereoscopic depth cues.
Claims21
A system comprising:
- a light guiding subsystem including a plurality of nonmagnetic specular reflectors;
- a housing to secure the light guiding subsystem;
- an entrance aperture in the housing to direct light from an external light source into the light guiding subsystem;
- and
- an exit aperture in the housing to direct light into a headbox, wherein the specular reflectors are non-magnetic, and the light forms a virtual image visible within the headbox.
The system of claim1, further comprising a mechanical joint to mount the housing to a medical imaging device.
A system comprising:
- a light guiding subsystem including a diffractive waveguide and a grating;
- a housing to secure the light guiding subsystem;
- an entrance aperture in the housing to direct light from an external light source into the light guiding subsystem;
- and
- an exit aperture in the housing to direct light into a headbox, wherein the specular reflectors are non-magnetic, and the light forms a virtual image visible within the headbox.
A system comprising:
- a field evolving (FEC) cavity having a non-magnetic reflector and a non-magnetic semi-reflector;
- a housing to secure the FEC;
- an entrance aperture in the housing to direct light from an external light source into the light guiding subsystem;
- and
- an exit aperture in the housing to direct light into a headbox, wherein the light forms a virtual image visible within the headbox.
