abstract:
The invention relates to a device and a method for testing the angle error of a hexagonal refraction drum, in particular to a method for testing the angle error of a hexagonal refraction drum by using a photoelectric autocollimator in an opportunistic digital vision reading system. The hexagonal refraction roller of the invention
An angle error testing device and method is characterized in that the device comprises an optical dividing head, a reflector, an objective lens, a spectroscope, a reticle, a condenser, an area CCD and a graph.
A sample acquisition device, a computer and a light source, wherein an objective lens, a reticle, a condenser and the light source are arranged in sequence; The beam splitter is arranged between the objective lens and the cross reticle; The reflector is arranged on the objective lens, and the hexagonal refractor is arranged on the optical indexing head.
Between drums; The area array CCD is arranged below the beam splitter; The image acquisition device is respectively connected with the area array CCD and the computer; The computer is connected with the reading controller of the optical indexing head. The angle error of the hexagonal refraction drum of the invention
The invention provides high-precision form and position error analysis data for production and scientific research departments.
