The invention relates to the technical field of precision engineering measurement, and provides a method for manufacturing a high-precision and large-diameter hollow cube-corner prism formed by gluing three plane reflectors, which comprises the following steps of: 1) detecting a naked mirror of a plane mirror and a surface type after framing; 2) establishing a test optical system, and coarsely adjusting a plane mirror assembly relation through a light spot imaging mode of a laser interferometer; 3) finely adjusting the relation of the plane mirror assembly through a CornCube measurement module of the laser interferometer; 4) dispensing the plane mirror assembly; 5) finely adjusting the relation of the plane mirror assembly through the CornCube measurement module of the laser interferometer again; 6) monitoring the curing process of the optical structural adhesive; and completing the manufacturing of the hollow cube-corner prism. The method has the advantages of real-time detection and direct evaluation, is simple to operate and high in precision, and is suitable for manufacturing high-precision and large-aperture hollow cube-corner prisms.
Description
Technical field [0001] The present invention relates to precision engineering measurement technology, and in particular, a method of making a large diameter and high precision hollow angle prism. Background technique [0002] The corner prism is configured vertically from three planes. Due to its structural characteristics, it has an arbitrary angle incident, and after the angular prism is reflected, the direction of the exit light is always parallel to the incident light direction, and therefore, significantly increase the measurement distance and ranging Accuracy, in the laser range finder, wavelengths are widely used. In the field of Fourier Optical Remote Sensing, the use of a gum prism replaces the motion mirror, which can significantly reduce the effects of motion mechanism on spectral detection, thereby increasing spectral detection accuracy. [0003] The method of producing the angle prism is mainly mainly used for optical processing, by grinding, polishing, cutting proce...
