The invention provides an angle reflector. The angle reflector includes a pedestal and at least two mirror bodies on the pedestal, wherein the pedestal is provided with a first reference surface; thefirst reference surface is provided with a first positioning structure part and a first mounting structure part; each mirror body is provided with a reflection surface, a second reference surface anda third reference surface; the second reference surface and the reflection surface has a 45 DEG included angle; the third reference surface is perpendicular to the reflection surface and the second reference surface; the reflection surfaces of the mirror bodies are mutually perpendicular to each other; the second reference surface is provided with a second positioning structure part and a second mounting structure part; the second positioning structure part and the first positioning structure part are mutually corresponding to each other, and positioning is realized through a positioning piece; and the second mounting structure part and the first mounting structure part are mutually corresponding to each other, fastened mounting is realized through a fastening piece. The angle reflector utilizes a working mode of total reflection, thus avoiding the propagation process of the light in the mirror body of a traditional angle reflector, effectively improving the light penetration efficiency, and reducing the requirement for consistency of raw materials of the mirror body. Besides, a manufacturing method of the angle reflector is provided.
Description
technical field [0001] The invention relates to the field of aerospace technology, in particular to a split-type high-precision corner reflector and a manufacturing method thereof. Background technique [0002] The main function of the corner reflector is to reflect the incident light back in the opposite direction in a compact space. At present, common corner reflectors (such as figure 1 shown) adopts the working mode of "transmission + reflection", and its working principle is as follows figure 2 As shown, the light first enters the interior of the corner reflector, passes through two mutually perpendicular reflecting surfaces for reflection and refraction in the interior of the mirror body, and finally returns along the reverse incident direction. [0003] Corner mirrors using the "transmission + reflection" working method have relatively large limitations, mainly reflected in: [0004] 1) Light is transmitted inside the mirror body, and there is an inevitable energy ...
