Anti-Vibration Optical System With Merged Reflective Members
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing anti-vibration optical systems for optical observation devices, such as binoculars, face challenges in reducing the number of reflective members to minimize size and weight while maintaining effective image stabilization, particularly in correcting image blurring caused by vibrations in multiple directions.
Innovation Solution
The proposed anti-vibration optical system uses a configuration with a first and second reflective member, where the first member is inclined to set a second optical axis, and the second member is inclined to set a third optical axis parallel to the first, allowing for image stabilization by rotating either member to correct blurring in one direction and integrating both for correction in orthogonal directions, thereby reducing the number of reflective members required.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If four reflective members are used in the anti-vibration optical system, then image blurring correction capability is improved, but device size and weight increase
Solution Approach 1:
The patent combines the functions of four separate reflective members into a single integrated reflective member. This reflective member has a first reflective surface for deflecting the optical axis in a first direction and a second reflective surface for deflecting the optical axis in a second direction, thereby merging multiple reflection functions into one component and reducing overall system weight and complexity
Solution Approach 2:
The single reflective member serves multiple functions by incorporating both the first reflective surface and the second reflective surface. This multi-functional design allows one component to perform the work of four separate reflective members, correcting image blurring in multiple directions simultaneously while reducing the number of parts needed
2Reliability
If four reflective members are used in the anti-vibration optical system, then image blurring correction capability is improved, but device complexity increases
Solution Approach 1:
The patent merges four separate reflective members into one integrated component with multiple reflective surfaces. This consolidation simplifies the overall structure by reducing the number of individual parts, assembly steps, and alignment requirements, thereby decreasing device complexity while maintaining the same image stabilization functionality
Solution Approach 2:
The integrated reflective member performs multiple functions that would otherwise require four separate components. By combining the optical path deflection functions in different directions into a single multi-functional element, the system achieves simpler structure and easier maintenance while preserving full image blurring correction capability
3Weight of moving object
If the number of reflective members is reduced, then device size and weight are decreased, but image blurring correction capability may deteriorate
Solution Approach 1:
The patent successfully merges the correction capabilities of four reflective members into one integrated component. The first reflective surface corrects image blurring in the first direction by deflecting the optical axis, while the second reflective surface corrects image blurring in the second direction, ensuring that full stabilization capability is maintained despite using fewer parts
Solution Approach 2:
The single reflective member is designed with multi-functionality to compensate for the reduced number of components. It simultaneously provides optical axis deflection in multiple directions through its multiple reflective surfaces, ensuring that image blurring correction effectiveness is preserved while achieving weight and size reduction

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This configuration effectively reduces the size and weight of the optical system while preventing optical image rotation, enabling stable observation despite reduced reflective members, thus improving portability and response speed.
Implementation Method 1
The first reflective member (15) is inclined with respect to a first optical axis (14a) of the objective optical system (12) and sets a second optical axis (14b) by deflecting the first optical axis (14a)
Implementation Method 2
The second reflective member (16) is inclined with respect to the second optical axis (14b) and sets a third optical axis (14c), which is parallel to the first optical axis (14a), by deflecting the second optical axis (14b)

AI summary
The object of the present invention is to provide an anti-vibration optical system, a telephoto optical system, a binocle (binoculars), and an anti-vibration unit that are capable of appropriate distant observation even in a case where the number of reflective members is reduced.In a telephoto optical system, an anti-vibration optical system, which is provided with a first reflective member and a second reflective member, is disposed between an objective optical system and an ocular optical system. The anti-vibration optical system corrects image blurring in a first direction (pitch direction) by rotating the first reflective member around a first rotary shaft, and corrects image blurring in a second direction (yaw direction), which is orthogonal to the first direction, by rotating the first reflective member and the second reflective member around a second optical axis.
