Problems solved by technology

Small aircraft such as UAVs are very sensitive to the weight of the load. Larger loads mean more fuel or power consumption. When the existing solid-structure corner cube reflectors are used on small aircraft such as UAVs as ranging or identifying targets, it will cause Its battery life will be greatly shortened

Embodiment Construction

[0021] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0022] Unless expressly stated otherwise, throughout the specification and claims, the term "comprising" or its conjugations such as "comprising" or "comprising" and the like will be understood to include the stated elements or components, and Other elements or other components are not excluded.

[0023] like Figure 1 to Figure 4 As shown, the icosahedral combined pyramid mirror according to the specific embodiment of the present invention is composed of twenty hollow pyramid mirror units, and the twenty hollow pyramid mirror units are respectively oriented in twenty directions. According to the optical reflection theory, after a beam of light strikes a reflective surface of the corner cone reflection unit, after a max...

Abstract

The invention discloses an icosahedron combination pyramid reflector. 20 hollow pyramid reflector units facing 20 directions are combined angle to angle so as to form the icosahedron combination pyramid reflector. Each hollow pyramid reflector unit is formed by three isosceles right triangle-shaped plane mirrors, wherein every two isosceles right triangle-shaped plane mirrors are perpendicular to each other so that a convex fixed outer surface and concave reflection inner surface are formed. As the icosahedron combination pyramid reflector is formed through combination of hollow pyramid reflector units angle to angle, compared with a solid pyramid reflecting prism, the icosahedron combination pyramid reflector can effectively reduce the weight, and can reduce the load when the icosahedron combination pyramid reflector is arranged on a small aircraft, such as an unmanned plane, as the distance measurement or identification target so that consumption of fuel or electric quantity during the flight process can be saved and then the working time of endurance is prolonged.

Description

technical field [0001] The invention relates to the field of reflective prisms, in particular to an icosahedron combined pyramid mirror. Background technique [0002] Most of the existing corner cube reflectors are cube corner reflectors with solid structure, which are made of transparent materials such as optical glass. Due to the solid material as a whole, they are heavy. For example, a glass corner reflector with a right-angle side length of 100mm has a weight of about 400g, and even if a lighter plexiglass material is used, its weight is about 200g. [0003] Since the corner cube reflecting prism can return the light beam that is directed to the reflecting working surface in any direction, it can be used as a cooperative target for optical ranging or identification. Especially used in aircraft such as UAVs, etc., it can be used as a cooperative target for ranging or identification. Small aircraft such as UAVs are very sensitive to the weight of the load. More load mean...
