Description

Technical Field

[0001] The invention relates to the technical field of lens polarization testing, and in particular to an optical lens residual polarization testing device. Background Art

[0002] Optical lenses are essential components in machine vision systems, which directly affect the quality of imaging and the implementation and effect of algorithms. Optical lenses can be divided into short-focus lenses, medium-focus lenses, and long-focus lenses based on focal length. They can be divided into wide-angle, standard, and telephoto lenses based on field of view. They can be divided into fixed-aperture fixed-focus lenses, manual-aperture fixed-focus lenses, automatic-aperture fixed-focus lenses, manual-zoom lenses, automatic-zoom lenses, automatic-aperture electric-zoom lenses, electric three-variable lenses, etc. Optical industrial lenses are widely used in the positioning and detection of objects with extremely high reflectivity. Polarization refers to the phenomenon that the vibration vector of the transverse wave is biased in certain directions. Polarization data directly affects the quality of optical lenses.

[0003] The current residual polarization test device for optical lenses can only achieve measurements within a limited angle range. For example, the common method of rotating the lens at fixed angle intervals for detection is not only not flexible in angle adjustment, but also has a limited detectable angle range. In some practical application scenarios, the incident light angles of the optical lens are diverse and complex, making it impossible for existing test devices to fully grasp the residual polarization characteristics of the lens at different incident angles.
