The invention relates to the technical field of precision engineering measurement, and provides a method for a high-precision, large-caliber hollow corner cube prism formed by gluing three plane mirrors, comprising the following steps: Step 1) Detecting the bare plane mirror and framing it The surface shape; step 2) build the test optical system, and roughly adjust the relationship between the plane mirror components through the spot imaging mode of the laser interferometer; step 3) fine-tune the relationship between the plane mirror components through the CornCube measurement module of the laser interferometer; step 4) implement the plane mirror components Glue dispensing; step 5) through the CornCube measurement module of the laser interferometer again, to fine-tune the relationship between the plane mirror components; step 6) to monitor the curing process of the optical structural adhesive; to complete the production of the hollow corner cube. The method has the advantages of real-time detection and direct evaluation, simple operation and high precision, and is suitable for the manufacture of high-precision and large-diameter hollow corner cubes.
Description
technical field [0001] The invention relates to the technical field of precision engineering measurement, in particular to a method for manufacturing a large-diameter, high-precision hollow corner cube. Background technique [0002] The corner cube prism is composed of three planes perpendicular to each other. Due to its structural characteristics, it has an incident angle at any angle. After being reflected by the corner cube prism, the direction of the outgoing light is always parallel to the direction of the incident light. Therefore, the measurement distance and ranging are significantly improved. It is widely used in laser rangefinders and wavelength meters. In the field of Fourier optical remote sensing, using a corner cube prism instead of a moving mirror can significantly reduce the influence of the moving mechanism on spectral detection, thereby improving the accuracy of spectral detection. [0003] The production method of the corner cube mainly adopts the method ...
