Description

One-dimensional visible light invisibility cloak based on holographic image principle

technical field

The invention mainly relates to the field of visible light invisibility materials and instruments, in particular to a one-dimensional visible light invisibility cloak based on the principle of holographic images.

Background technique

Invisibility may be one of the oldest concepts in ancient mythology, but for at least a century physicists have dismissed the possibility of invisibility cloaks, asserting that they are impossible: they violate the laws of optics, And does not match the properties of any known substance. Now, an advance in "metamaterials" is making it possible to make the visible invisible. The invisibility of the prior art is based on the following ideas: (1) the use of "metamaterials" with a negative refractive index to achieve invisibility; (2) the realization of refraction invisibility in visible light, especially in the red light band; (3) the realization of invisibility through plasmonic photons ; The invisibility technology of the prior art cannot realize visible light invisibility in one-dimensional space, so it is of great value to design an invisibility cloak with visible light invisibility.

Contents of the invention

The technical problem to be solved by the present invention is: aiming at the technical problems existing in the prior art, the present invention provides a one-dimensional visible light invisibility cloak with reasonable structure and capable of realizing invisibility in one-dimensional space direction for visible light.

In order to solve the above problems, the solution proposed by the present invention is: a one-dimensional invisible cloak based on the principle of holographic images, which includes an inner protective layer, a signal transmission layer, and a front camera layer installed outside the inner protective layer. and a rear camera layer, a front display layer installed outside the front camera layer, and a rear display layer installed outside the rear camera layer.

The front camera layer is used to take pictures of the scene outside the front display layer, and transmit the imaging to the rear display layer in real time through the signal transmission layer; The scene outside the rear display layer is photographed, and the imaging is transmitted to the front display layer in real time through the signal transmission layer.

The front camera layer can take pictures in the range of 120 degrees in front of it, and the rear camera layer can take pictures in the range of 120 degrees in front of it; the structure of the front camera layer and the rear camera layer is the same , the interior is equipped with n 3D high-speed cameras and microprocessors, which can quickly process n photos taken at the same time; the structure of the front display layer is the same as that of the rear display layer, and nano-coating can be used Display, plasma display can also be used.

Compared with the prior art, the present invention has the following advantages and beneficial effects:

(1) The one-dimensional visible light invisibility cloak based on the holographic image principle of the present invention is provided with a front camera layer and a rear display layer, which can image the scene in front on the rear display layer, thereby implementing one-dimensional reverse visible light invisibility .

(2) The one-dimensional visible light invisible cloak based on the holographic image principle of the present invention is also provided with a front display layer and a rear camera layer, which can image the scene behind the invisible cloak on the front display layer, thereby realizing Visible light invisibility in one-dimensional positive direction. It can be seen from the above that the present invention has a reasonable structure and is capable of realizing invisibility in one-dimensional direction for visible light in one-dimensional visible light invisibility cloak.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

Referring to Fig. 1 and Fig. 2, the one-dimensional visible light invisible cloak based on the holographic image principle of the present invention includes an inner protective layer 3, a signal transmission layer 4, a front camera layer 2 and a rear camera layer installed outside the inner protective layer 3. The camera layer 5, the front display layer 1 installed outside the front camera layer 2, the rear display layer 6 installed outside the rear camera layer 5; the front camera layer 2 is used for displaying the front display layer 1 The external scene is photographed, and the imaging is transmitted to the rear display layer 6 in real time through the signal transmission layer 4; Pass it to the front display layer 1.

Referring to Fig. 1 and shown in Fig. 2, the front camera layer 2 can take pictures within the scope of 120 degrees directly ahead of it, and the rear camera layer 5 can take pictures within the scope of 120 degrees directly ahead of it; The structure of layer 5 is the same, and n 3D high-speed cameras and microprocessors are installed inside, which can quickly process n photos taken at the same time; the structure of front display layer 1 and rear display layer 6 is the same, and can be used Nano-coating display, plasma display can also be used.

Working principle: Assuming that A is located directly in front of the invisibility cloak, since the rear camera layer 5 takes real-time pictures of the scene within 120 degrees outside the rear display layer 6, and at the same time images the image on the front display layer 1 through the signal transmission layer 4, at this time Although A's eyes are facing the invisibility cloak, he can "pass through" the invisibility cloak and directly see all the scenes in the 120-degree range behind the invisibility cloak, as if the invisibility cloak does not exist. Therefore, for A's research, the invisibility is realized; suppose A is located directly behind the invisibility cloak. According to the above-mentioned similar principles, the front camera layer 2 takes pictures of the scene outside the front display layer 1, and the image is imaged on the rear display layer 6. A can "pass through" the invisibility cloak to see other scenes The scene ahead.
