AI Technical Summary
Technical Problem
When existing telescopes shake, optical image stabilization technology changes the focal length and imaging of the optical system, resulting in poor image stabilization convenience and increased weight and size of the optical system.
Method used
A liquid variable prism is used, positioned horizontally between the objective lens and the eyepiece. By changing the slope of the prism surface, the optical axis direction is adjusted to compensate for optical axis deviation caused by jitter, thus avoiding the need to redesign the optical system.
Benefits of technology
It improves the ease of image stabilization for optical systems and telescopes, reduces the increase in the size and weight of optical systems, and enhances the user experience.

Abstract
The application relates to the field of telescopic technology and discloses an optical system and a telescope. The optical system comprises an objective lens, a liquid variable prism and an eyepiece. The liquid variable prism is located between the objective lens and the eyepiece in the horizontal direction. The liquid variable prism has a plurality of prism surfaces, and the slope of at least one prism surface in the plurality of prism surfaces can be changed. The liquid variable prism is used for changing the slope of the at least one prism surface, so as to change the optical axis direction of the optical system, so that the light emitted or reflected by a target object is transmitted to the human eye after the action of the optical system after the change of the optical axis direction. In the case that the optical axis direction deviates due to the shaking of the optical system, the slope of the at least one prism surface of the liquid variable prism is changed to change the optical axis direction of the optical system, and then the angle deviation amount corresponding to the optical axis direction of the optical system when the shaking occurs is compensated by using the angle change amount corresponding to the optical axis direction of the optical system, so that the anti-shaking convenience of the optical system is improved.
