Optic camouflage device and manufacturing method therefor

Abstract

The invention discloses an optical cloaking device and a preparation method thereof. The optical cloaking device comprises a plurality of tightly parallel and bonded total reflection optical fibers and a storage space formed by bending the middle part of the total reflection optical fiber. A human body or an object can be hidden, and the two ends of the total reflection optical fiber straddling the storage space are arranged in alignment. When preparing, first select a plurality of total reflection optical fibers with a diameter of 0.01-0.5 mm; then bend the middle part of the total reflection optical fiber; then closely adhere a plurality of total reflection optical fibers bent in the middle in parallel, and the curved part forms a storage space . The present invention adopts the fully reflective optical fiber tightly parallel and bonded, which guarantees the stealth technology and effect and does not require external energy, and has a wide range of applications; the optical fiber has a total reflection effect, and the corresponding scene behind the device can be seen at any angle; the total reflection The two ends of the optical fiber are arranged in alignment, which can reduce the reflection and scattering of light, and facilitate the entry, transmission and clear imaging of light.

Description

technical field [0001] The invention relates to the field of optical cloaking, in particular to an optical cloaking device and a preparation method thereof. Background technique [0002] Invisibility has always been a human dream. In recent years, stealth stealth technology has been gradually used. However, most of the stealth and stealth technologies in the field of military industry and national defense are radar stealth rather than optical stealth. In the civilian field, most of the stealth technologies we use are the method of using a camera to capture the scene on the back and then display it on the front of the display, such as Chinese patents 2009202226191, 2014101429565, and 2014200133371. These patents provide the advantages and benefits of their respective methods, but they still cannot avoid the common disadvantages of such methods, such as the need for continuous power supply, the need to install numerous small displays, and the need to know the view angle of t...
