Augmented reality telescope Technical Field The application relates to the technical field of telescopes, in particular to an augmented reality telescope. Background At present, the telescope is used as an important optical instrument and plays a key role in various fields such as astronomical observation, military reconnaissance, outdoor exploration and the like. With the continuous progress of technology, the performance and the function of the telescope are continuously improved, the telescope is gradually developed from an initial simple optical structure to a complex system integrating various advanced technologies, a stronger tool is provided for exploring the unknown world, and the visual field range of human beings is greatly expanded. In the related art, in order to meet different observation requirements, various ways are generally used to achieve different imaging effects. For example, some astronomical telescopes may be provided with structures such as objective lenses, ocular lenses, star finding lenses, reflectors, corner mirrors, and displacement assemblies. The objective lens is used to collect light and form an initial image, and the eyepiece lens is used to magnify the image for observation by an observer. The star finder helps observers to find a target celestial body quickly, the direction of the light path is changed through elements such as a plane reflector, and the shifting assembly can realize movement of certain parts to adjust the observation effect. Still other telescopes achieve different magnification and imaging quality by different optical lens combinations and adjusting the position of the lenses. Aiming at the related technology, although the scheme realizes the switching of the optical paths, the function of the scheme is still single in nature, the problem of switching between the two traditional optical functions of main measurement and auxiliary star finding is only solved, a truly diversified imaging mode cannot be provided, and the diversified observation requirement of users is difficult to meet.
