Abstract

The invention provides an infrared/visible dual-waveband photoelectric self-aligning system, which comprises a light source, a beam splitter, a secondary lens, a protection window, a main lens and a reading imaging device, wherein the beam splitter is positioned on the radiation light path of the light source; the secondary lens is positioned on the reflecting light path of the beam splitter; the protection window is used for fixing the secondary lens; the main lens is positioned on the reflecting light path of the secondary lens; the main lens is used for reflecting parallel beams; the reading imaging device is arranged on the transmitting light path of the beam splitter; the reflecting surface of the main lens is a paraboloid; the secondary lens has a hyperboloid structure. By adopting the infrared/visible dual-waveband photoelectric self-aligning system, the requirement of visible and infrared parallel light source testing can be met. The infrared/visible dual-waveband photoelectric self-aligning system can be used as an infrared/visible parallel light tube as well as an infrared/visible light self-aligning system.

Description

technical field [0001] The invention belongs to the field of optics and relates to an autocollimation system. Background technique [0002] The traditional autocollimation optical system is an autocollimation system with a single working band, which projects an image of a reticle in the form of a parallel beam (collimated light) onto a mirror (object under test), which is object) reflects its beam back to the autocollimator. This is the autocollimated image. If the mirror (object under test) is perpendicular to the optical axis, the beam will reflect back on itself; if the mirror (object under test) is tilted at an angle, its reflected light will reflect back at an angle. Depending on how tilted the reflected light is, the autocollimated image is displaced by a larger or smaller angle. The angle change of the mirror (object under test) can be measured by measuring the displacement of the self-collimation image on the X-axis and Y-axis. Generally, the system can only comp...
