[0036] Such as figure 1 As shown, the detection device of the large-aperture reflective optical system based on the corner cube array of the present invention is composed of the corner cube array 1, the large-aperture reflective optical system to be measured, and the point light source transmitting and receiving device 3.
[0037] The corner cube array 1 includes a plurality of corner cubes arranged in a matrix (the corner cube is formed by cutting a corner of a cube), and the corner cube includes three cone surfaces and a bottom surface. The two cones are perpendicular to each other, and the bottom is an isosceles triangle;
[0038] The bottom surfaces of all corner cubes in the corner cube array 1 are facing the large-aperture reflective optical system 2 to be measured (for any corner cube: the incident light beam entering the corner cube at any angle is incident from its bottom surface and passes through the three corners. After the cones are reflected in turn, they still emerge...
