Title:
OPTICAL AXIS CALIBRATION METHOD FOR REFLECTIVE TELESCOPE
Document Type and Number:
WIPO Patent Application WO/2021/190330
Kind Code:
A1
Abstract:
An optical axis calibration method for a reflective telescope. The method comprises: acquiring a real-time eyepiece image in an eyepiece optical axis direction and displaying same (S1); drawing a reference circle with the center point of the real-time eyepiece image serving as the center of the circle, and drawing a cross-shaped calibration line with the center point of the real-time eyepiece image serving as the center (S2); and adjusting a secondary mirror and a primary mirror, such that a secondary mirror reflection surface boundary circle, a primary mirror reflection circle and a primary mirror center mark in the real-time eyepiece image are respectively concentrically arranged with respect to the reference circle, and the projection of a secondary mirror fixing holder in the real-time eyepiece image overlaps with the cross-shaped calibration line (S3). By means of the calibration method, the optical axis calibration of a reflective telescope can be rapidly completed, which has a strong operability. A real-time eyepiece image is transmitted to a display device for display, such that the image can be observed very conveniently. Compared with a traditional calibration method, the method provides a clearer calibration base line and has a higher efficiency.
