Embodiment Construction

[0022]In accordance with one or more embodiments described herein, a cloaking device may generally include a converging lens pair on the object side of the cloaking device, a converging lens pair on the image side of the cloaking device, and a coherent image-guiding system that directs incident light around the cloaking region. pieces. The cloaking devices described herein may utilize plano-convex and / or Fresnel lenses to focus, diverge, and refocus light from objects. The cloaking device can be used to cloak vehicle items (such as vehicle A-pillars, B-pillars, C-pillars, D-pillars, etc.) and remove "blind spots" caused by vehicle items. A blind spot is an area of ​​a vehicle that may block a passenger's view. The use of converging lenses and coherent image guides allows the driver to perceive images that would otherwise be blocked by vehicle pillars without the cloaking device. Various embodiments of cloaking devices and methods of using them will be described in further de...

Abstract

The present invention relates to a cloaking device with converging lenses and coherent image guides and vehicles comprising the same. The present invention provides a cloaking device with an object-side, an image-side, and a cloaked region. A first object-side converging lens and a second object-side converging lens are positioned on the object-side, and a first image-side converging lens and a second image-side converging lens are positioned on the image-side. A coherent image guide with an object-side end optically aligned with the second object-side converging lens and an image-side end optically aligned with the second image-side converging lens is included. Light from an object positioned on the object-side of the cloaking device is focused in parallel onto the object-side end of thecoherent image guide by the first object-side converging lens and the second object-side converging lens, propagates through the coherent image guide, and is focused in parallel by the second image-side converging lens and the first image-side converging lens to form an image of the object on the image-side of the cloaking device.

Description

technical field [0001] The present description relates generally to apparatus and methods for making objects appear transparent, and more particularly to cloaking apparatus for vehicle pillars and methods for making vehicle pillars appear transparent. Background technique [0002] Research into a cloaking device that appears to make vehicle pillars transparent has been published. Such research discloses the use of metamaterials or the use of cameras in combination with display screens to allow occupants of a vehicle to ostensibly "see through" vehicle pillars, thereby reducing blind spots in vehicles. However, metamaterials and video technologies use complex material design and rigging. [0003] Thus, there is a need for alternative devices that appear transparent to vehicle pillars. Contents of the invention [0004] In one embodiment, the cloaking device includes an object side, an image side, and a cloaking area. A first object-side converging lens having a first obj...
