AR Telescope Optics for Eyepiece Image Plane Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional telescopes with augmented reality (AR) technology face issues of inconvenient use, low comfort during viewing, and poor image quality due to external or built-in display screens that require line-of-sight adjustment and cause eye discomfort and scene distortion.
Innovation Solution
A telescope augmented reality optical system with two optical path systems: a telescopic path for viewing and an AR path for superimposed information, using a Pechan prism group, a beam splitter prism with specific angles, and a refractor assembly to project extended function information directly onto the eyepiece image plane, employing cemented doublet or aspherical lenses and a beam splitting film to enhance image quality and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an external display screen is used to show extended function information, then the information can be displayed, but the user must move the line of sight to view the information, leading to inconvenient use
Solution Approach 1:
The patent merges the extended function information display with the telescopic optical path by projecting the information directly onto the eyepiece image plane. This allows the information to be viewed through the same optical path as the telescopic scene, eliminating the need to move the line of sight between separate displays and the telescopic view.
2Loss of information
If a built-in display screen is combined with the telescopic optical path, then the information can be viewed during telescopic viewing, but the display screen causes scene distortion and reduces image quality
Solution Approach 1:
The patent segments the optical path into two separate projection systems: one for the telescopic scene and one for the extended function information. Both projections converge on the same image plane without interfering with each other, allowing information display while maintaining scene image quality without the distortion caused by combining displays in the optical path.
3Loss of information
If a built-in display screen is added to the telescopic optical path, then extended function information can be displayed, but the imbalance between left and right optical paths causes eye discomfort
Solution Approach 1:
The patent employs asymmetric optical path design where the AR information projection is superimposed on the telescopic optical path in a way that maintains balance between left and right eyes. The projection system is configured to ensure equal optical path lengths and identical magnification for both eyes, eliminating the imbalance that causes eye discomfort.

AI summary
The present invention relates to an optical system, and specifically, to a telescope augmented reality optical system. A telescope augmented reality optical system comprises two optical path systems. One optical path system is a telescopic optical path system for realizing a telescopic function, and the other optical path system is an AR optical path system for realizing superimposed extended function information. Compared with a conventional technology, the present invention has the following beneficial effects: The telescope AR optical system of the present invention is easy to use, provides comfortable viewing experience, and produces clearer imaging. In the present invention, a projecting method is used. The extended function information is projected onto an eyepiece image plane, so as to be superimposed with the scene content. The superimposed image is magnified by an eyepiece group and then enters the human eye. In this way, a user can directly view a distant scene and the extended function information through an eyepiece.
