Virtual Display Device for Telescopic Sight Simultaneous Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current telescopic sights require shooters to divert their gaze from the target to access shooting information, reducing efficiency due to the limitations of eye relief and the inability to simultaneously view both the target and display screen contents.
Innovation Solution
A virtual displaying device integrated with the telescopic sight, featuring a sleeve and member with lenses and mirrors that project display screen information alongside the eyepiece light, allowing shooters to see both the target and display content within the eye relief distance, enhancing shooting efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If a displaying screen is positioned next to the eyepiece of the telescopic sight, then the shooter can view shooting information, but the shooter cannot simultaneously see the actual object and the display content due to eye relief limitations
Solution Approach 1:
The patent transforms the display from a 2D screen positioned laterally next to the eyepiece into a virtual image projected into the 3D optical path through the eyepiece. By using optical elements (beam splitter, lenses) to project the display content into the shooter's field of view, the system allows simultaneous viewing of both the target and shooting information without requiring lateral screen placement, thus resolving the eye relief distance conflict.
Solution Approach 2:
The patent introduces optical intermediary elements (beam splitter, projection lenses, and the eyepiece itself) to mediate between the display screen and the shooter's eye. These intermediaries combine the display light path with the optical sight path, allowing both the target image and display content to be superimposed and viewed simultaneously through the same optical channel, eliminating the need to choose between viewing the target or the display.
2Loss of information
If the shooter removes his eyesight from the target to check shooting information, then the shooter can obtain accurate data, but the shooting efficiency is greatly reduced
Solution Approach 1:
The patent enables continuous viewing of both the target and shooting information simultaneously through the telescopic sight without interruption. By projecting the display content into the optical path, the shooter maintains unbroken visual contact with the target while continuously accessing shooting data (distance, trajectory, wind information), eliminating the need to shift gaze or pause for information retrieval, thus maintaining continuous shooting readiness.
Solution Approach 2:
The patent merges the display information viewing function with the target viewing function into a single integrated optical system. Both the shooting information and the target image are combined and presented through the same eyepiece, allowing the shooter to access accurate shooting data without breaking the line of sight to the target, thereby maintaining shooting efficiency and readiness.
3Loss of information
If a displaying screen is placed within 6-12 cm from the shooter's eye for direct viewing, then the display can be seen, but the shooter cannot see the actual object within this distance
Solution Approach 1:
The patent projects the display content from a physical screen positioned at a fixed distance into a virtual image space that appears to be located at optical infinity or at a comfortable viewing distance through the eyepiece. This dimensional transformation allows the display information to be viewed simultaneously with the target at any distance without being constrained by the physical screen placement distance from the eye.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables shooters to obtain and utilize shooting information without removing their gaze from the target, improving accuracy and efficiency by providing simultaneous visibility of the target and display content within the telescopic sight's eye relief.
Implementation Method 1
light emitted from the displaying screen passing through the concave lens to be diverged
Implementation Method 2
then passing through the convex lens to be converged
Implementation Method 3
Light emitted from the displaying screen passes through the member to be zoomed and shifted

AI summary
A virtual displaying device used on a telescopic sight includes a sleeve sleeved around an eyepiece portion of the telescopic sight, a virtual assembly and a fixing portion for fixing the sleeve and the virtual assembly to the eyepiece portion. The virtual assembly includes a housing, a virtual member and a displaying screen both received in the housing. Light emitted from the displaying screen passes through the virtual member to be zoomed and then is simultaneously imaged, together with light of the eyepiece, near distance of exit pupil of the telescopic sight so that a shooter can simultaneously and clearly see both the target inside the eyepiece and contents displayed on the displaying screen. The present structure above can allow the shooter to achieve important shooting information while aiming at a target and greatly improve the efficiency of the telescopic sight.
