Abstract
An optical system and methods are disclosed. In an aspect, an optical system can comprise a display device configured to emit an image information and an image guide optically coupled to the display device, wherein the image guide is configured to receive the image information and transmit the image information along a longitudinal axis of the image guide, and wherein the image guide has a thickness along a lateral axis between about 0.3 mm and about 1 mm. The optical system can further comprise a beam combiner disposed in the image guide, the beam combiner configured to transmit at least a portion of the received image information to exit the image guide.
Claims22
A system for use in eyewear, said eyewear including a lens that passes see through images, said system comprising:
- a display device that emits image information of an object;
- an image guide optically coupled to the display device, wherein the image guide is configured to receives the image information, transmit the image information along a longitudinal axis of the image guide via multiple reflections, form, with respect to a direction normal to the longitudinal axis, two symmetrical output images of the object in the image information from the display device, and superimpose at least one of the output images over the see through images for viewing;
- and
- a beam combiner disposed in the image guide, the beam combiner configured to receive the image information transmitted through the image guide and transmit only a portion of the received image information from the image guide, so that only one of the two symmetrical output images of the object in the image information is transmitted and superimposed over the see through images for viewing by a user and the remaining one of the two symmetrical output images of the object in the image information is eliminated from a field of view of the user;
- wherein the beam combiner comprises a hologram, or a mirror having a tilt angle to the longitudinal axis of the image guide, said mirror or hologram configured such that one of the two symmetrical output images of the single object in the image information is transmitted outside the field of view of the user.
A method for superimposing image information from a display device over another image for viewing, comprising:
- receiving image information of an object, from a display device, by an image guide;
- transmitting the image information along a longitudinal axis of the image guide via total internal reflection;
- forming, with respect to a direction normal to the longitudinal axis, two symmetrical output images of the object in the image information from the display device;
- superimposing at least one of the output images over another image not from the display device for viewing;
- and
- receiving, using a beam combiner disposed in the image guide, the image information transmitted through the image guide and transmitting only a portion of the image information received from the image guide, so that only one of the two symmetrical output images of the object in the image information is transmitted and superimposed over the another image not from the display device for viewing by a user and the remaining one of the two symmetrical output images of the object in the image information is eliminated from a field of view of the user;
- wherein the beam combiner comprises a hologram, or a mirror having a tilt angle to the longitudinal axis of the image guide, said mirror or hologram configured such that one of the two symmetrical output images of the single object in the image information is transmitted outside the field of view of the user.
