Abstract
Described herein are embodiments of displays which may be used in high pressure environments, e.g., in underwater environments, and systems which utilize such displays. In some embodiments, a system comprises at least one electronic device comprising an optical output, a first optical interface to couple the optical output to an optical transmission medium, a second optical interface coupled to the optical transmission medium, and a display coupled to the second optical interface. In some embodiments the second optical interface comprises a material having a graded index of refraction, and the display comprises an optically transmissive material coupled to the second optical interface to transmit an image from the second optical interface to a reflective surface.
Claims20
A system, comprising:
- at least one electronic device comprising an optical output;
- a first optical interface to couple the optical output to an optical transmission medium;
- a second optical interface coupled to the optical transmission medium;
- and
- a display coupled to the second optical interface, wherein:
- the second optical interface comprises a material having a graded index of refraction;
- and
- the display comprises an optically transmissive material coupled to the second optical interface to transmit an image from the second optical interface to a reflective surface, wherein:
- the first optical interface is disposed inside a hull of a waterborne vehicle;
- and
- the second optical interface is disposed outside the hull of the waterborne vehicle;
- and
- the optical transmission medium provides an optical path through the hull of the waterborne vehicle.
A display, comprising:
- an optical interface comprising a material having a graded index of refraction to receive an optical signal from a remote source;
- a optically transmissive material coupled to the optical interface to transmit an image from the optical interface;
- and
- a substantially planar reflective surface coupled to the optically transmissive material to reflect the image onto a substantially planar viewing surface;
- and
- a protective surface disposed over the viewing surface, the protective surface comprising a material having a refractive index which varies as a function of a distance from an end of the protective surface.
A system, comprising:
- at least one electronic device comprising an optical output;
- a first optical interface to couple the optical output to an optical transmission medium;
- a second optical interface coupled to the optical transmission medium;
- and
- a display coupled to the second optical interface, wherein:
- the second optical interface comprises a material having a graded index of refraction;
- and
- the display comprises an optically transmissive material coupled to the second optical interface to transmit an image from the second optical interface to a reflective surface,
- wherein the display comprises a protective surface disposed over the viewing surface and the protective surface comprises a material having a refractive index which varies as a function of a distance from an end of the protective surface.
