Riflescope Display Using Perpendicular Light and Mirror
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sophisticated riflescopes face challenges in providing substantial information to users without obstructing their view of the live scene, as advanced electronic components complicate the presentation of data in an unobtrusive manner.
Innovation Solution
Incorporating an internal display system with a mirror positioned between focal planes, emitting light perpendicular to the optical axis and reflecting it to the ocular system, allowing for non-parallel light emission and reflection to present information without obstructing the user's view, while maintaining flexibility in component placement and minimizing display visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If an internal display system is incorporated to provide substantial information to the user, then the quantity of information provided is improved, but the view of the live scene becomes obstructed
Solution Approach 1:
The display is positioned perpendicular to the optical axis, emitting light in a direction substantially perpendicular to the optical axis of the riflescope. The mirror is oriented at an angle of approximately 45° relative to the emitted light, redirecting display information into the optical path without blocking the live scene view through dimensional separation of information display and scene viewing paths
Solution Approach 2:
A mirror is introduced as an intermediary element positioned between the display and the ocular system. The mirror reflects light from the display at approximately 45° angle, serving as a mediator that directs display information into the optical path without the display itself blocking the user's view of the live scene
2Object-affected harmful factors
If the display emits light perpendicular to the optical axis and uses a mirror for reflection, then the display visibility is minimized, but the device complexity increases
Solution Approach 1:
The display is positioned perpendicular to the optical axis rather than parallel, changing the dimensional orientation of light emission. This perpendicular arrangement allows the display to emit light at 90° to the optical axis, minimizing visibility while enabling mirror reflection at 45° to redirect information into the optical path
Solution Approach 2:
The mirror is oriented at an asymmetric angle of approximately 45° relative to the emitted light from the display, creating an asymmetric optical path that redirects display information into the optical path without symmetric blocking of the live scene view

Function Achieved in This Case
Enables the provision of essential information, such as adjusted settings and environmental conditions, to the user without requiring them to lift their eye from the riflescope, ensuring an unobstructed view and efficient use of power through high contrast reflection at lower luminance levels.
Implementation Method 1
the mirror is oriented at an angle of approximately 45° relative to the emitted light of the display

AI summary
A riflescope having a display that provides information to a user of the riflescope, along with related methods, is provided herein. In one embodiment, a riflescope includes an objective system and an ocular system, wherein a focal plane is defined between the objective system and the ocular system. A display system, comprising a display and a mirror, is positioned at a location between the focal plane and the ocular system. In one embodiment, the distance between the focal plane and the ocular system is equal to a sum of a distance between the display and the mirror and a distance between the mirror and the ocular system.
