Problems solved by technology

Its characteristic is that the invisible space formed by the combination of isosceles triangles with different vertex angles is closed, and the increase of the scale of the invisible space must be realized by increasing the size of isosceles triangles with different vertex angles, which will inevitably increase the manufacturing cost

Embodiment 1

[0020] Such as Figure 1-2 As shown, the large-scale open optical cloaking device of this embodiment is composed of a base 1, a luminous uniform light drawing board 2, a right triangular water tank 3, a V-shaped water tank 4, and a left triangular water tank 5. In order to further understand the present invention, the viewing direction is defined as the front side of the V-shaped water tank 4 .

[0021] The front side on the base 1 is equipped with a V-shaped water tank 4 and a luminous uniform light drawing board 2 installed on the rear side. The luminous uniform light drawing board 2 is opposite to the V-shaped opening of the V-shaped water tank 4, and the V-shaped water tank 4 is glued by a transparent glass plate. Structurally, fill water in the V-shaped water tank 4, the geometric shape of the V-shaped water tank 4 is a cuboid whose rear side wall is a vertical V-shaped groove, and the angle between the two sides of the V-shaped groove is 90 °, and the V-shaped groove Th...

Embodiment 2

[0027] A V-shaped water tank 4 is installed on the front side of the base 1, and a light-emitting uniform light drawing board 2 is installed on the rear side. The light-emitting uniform light drawing board 2 is opposite to the V-shaped opening of the V-shaped water tank 4, and the V-shaped water tank 4 is filled with water. , the geometric shape of the V-shaped water tank 4 is that the rear side wall is a cuboid with a vertical V-shaped groove, the angle between the two sides of the V-shaped groove is 90 °, the distance between the top of the V-shaped groove and the 4 front side walls of the V-shaped water tank The distance h is 10mm. The front side wall of the V-shaped water tank 4 is perpendicular to the left side wall and the right side wall, and the left side wall of the V-shaped water tank 4 is the same as the width of the right side wall, and the left side wall of the V-shaped water tank 4 is the same as the left side wall of the V-shaped tank. The included angle between...

Embodiment 3

[0031] Such as image 3 As shown, a V-shaped water tank 4 is installed on the front side of the base 1, and a light-emitting uniform light drawing board 2 is installed on the rear side. The light-emitting uniform light drawing board 2 is opposite to the V-shaped opening of the V-shaped water tank 4. Filled with water, the geometric shape of the V-shaped water tank 4 is a cuboid whose rear side wall is a vertical V-shaped groove, and the angle between the two sides of the V-shaped groove is 90 °, the top of the V-shaped groove and the front side wall of the V-shaped water tank 4 The distance h between them is 20mm. The front side wall of the V-shaped water tank 4 is perpendicular to the left side wall and the right side wall, and the left side wall of the V-shaped water tank 4 is the same as the width of the right side wall, and the left side wall of the V-shaped water tank 4 is the same as the left side wall of the V-shaped tank. The included angle between is 45 °, and the in...

Abstract

Provided in the invention is a large-scale open type light stealth device. A V-shaped water tank is formed in the rear side of a pedestal and a light-emitting dodging plate in opposite to a V-shaped opening of the V-shaped water tank is arranged at the front side of the pedestal. A right triangular water tank and a left triangular water tank that are symmetric mutually by using the midperpendicular surface of the V-shaped water tank as a central surface and have the same structures are arranged between the V-shaped water tank and the light-emitting dodging plate; the front right-angle side wall of the left triangular water tank is parallel to the V-shaped left side wall of the V-shaped water tank; the front right-angle side wall of the right triangular water tank is parallel to the V-shaped right side wall of the V-shaped water tank; and space is encircled by the left side wall of the left triangular water tank, planes of the two right-angle side walls of the left triangular water tank, the right side wall of the right triangular water tank, and planes of the two right-angle side walls of the right triangular water tank and the space is stealth space. According to the invention, the distance between the V-shaped water tank and the light-emitting dodging plate and the distance between the right triangular water tank and the left triangular water tank are increased synchronously,so that extension of the stealth space is realized. The device has advantages of simple structure and low cost.

Description

technical field [0001] The invention belongs to the technical field of optical stealth, and in particular relates to a large-scale open optical stealth device and a stealth scale debugging method thereof. Background technique [0002] "Invisibility" has been a dream of mankind for a long time. Through the unremitting efforts of scientists, stealth technology has made progress in different fields. However, the existing stealth technology is mainly in the microwave band. By coating the surface of the aircraft with materials that can absorb radar waves, the aircraft is prevented from being detected by radar, so as to realize the stealth of the aircraft. However, this technology is not true stealth. In the visible light band, the aircraft is still is visible. Japanese scientists have developed a stealth device, which uses a camera installed on the back of the body and uses the cover of the human body as a display to capture the image of the back of the human body and display it...
