Augmented reality (AR) eyewear with a section of a fresnel reflector comprising individually-adjustable transmissive-reflective optical elements
Disclosed herein is augmented reality (AR) eyewear with at least one array of individually-adjustable optical elements whose levels of light transmission and/or reflectivity are selectively and individually adjusted by application of electrical current, or by exposure to an electromagnetic field, via transparent (or translucent) electroconductive pathways. Optical elements in this array collectively comprise a section of a Fresnel Reflector which has been selected (e.g. extracted or “cut out”) from the right side or the left side of a Fresnel Reflector.
1. Augmented reality eyewear comprising:
a light-emitting display;
an array of individually-adjustable transmissive-reflective optical elements, wherein the array of individually-adjustable transmissive-reflective optical elements collectively comprise a section of a Fresnel Reflector, wherein each optical element in the array has a first configuration which transmits a first level of light from the environment to the person's eye and reflects a second level of light from the display toward the person's eye, wherein each optical element in the array has a second configuration which transmits a third level of light from the environment to a person's eye and reflects a fourth level of light from the display toward the person's eye, wherein the third level is less than the first level, wherein the fourth level is greater than the second level, and wherein each optical element in the array can each be individually and selectively changed from the first configuration to the second configuration, or vice versa; and
an array of transparent or translucent electroconductive pathways, wherein each optical element in the array of optical elements can be individually and selectively changed from the first configuration to the second configuration, or vice versa, by exposure to electrical current and/or an electromagnetic field via one or more electroconductive pathways in the array of electroconductive pathways.
2. The augmented reality eyewear in claim 1 wherein the section of a Fresnel Reflector is a section of a right side or a left side of the Fresnel Reflector.
3. The augmented reality eyewear in claim 1 wherein the size of the section of a Fresnel Reflector is less than 25% of the overall size of the Fresnel Reflector.
4. The augmented reality eyewear in claim 1 wherein display-facing angles between best-fitting planes of optical elements and a best-fitting plane of the array of optical elements, respectively, are a linear function of distances from the optical elements to the display.
5. The augmented reality eyewear in claim 1 wherein display-facing angles between best-fitting planes of optical elements and a best-fitting plane of the array of optical elements, respectively, are a negative linear function of distances from the optical elements to the display.
6. The augmented reality eyewear in claim 1 wherein display-facing angles between best-fitting planes of optical elements and a best-fitting plane of the array of optical elements, respectively, are a quadratic function of distances from the optical elements to the display.
7. The augmented reality eyewear in claim 1 wherein an optical element in the array of optical elements is changed from the first configuration to the second configuration, or vice versa, by electrical current from one or more electroconductive pathways in the array of electroconductive pathways.
8. The augmented reality eyewear in claim 1 wherein an optical element in the array of optical elements is changed from the first configuration to the second configuration, or vice versa, by exposure to an electromagnetic field created by one or more electroconductive pathways in the array of electroconductive pathways.
