See-Through Binocular Optics for Far-to-Near Field Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional binoculars fail to provide binocular vision for objects at intermediate and near distances, leading to uncomfortable viewing due to separate non-overlapping fields of view and inability to focus images at these distances.
Innovation Solution
A see-through binocular device with two optical modules, each featuring a variable optical power element and a projection system, ensuring equal output optical axes and intersecting input axes at a near distance to achieve complete field of view overlap for near distances, with optional features like multifocal vision and adjustable interpupillary distance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional binoculars are used for far distance vision with high magnification, then magnification is improved, but field of view decreases and binocular vision is lost at intermediate and near distances
Solution Approach 1:
The patent implements dynamic adjustment of the optical system to change the field of view and focal plane based on the distance to the object being observed. The binocular device can switch between a first configuration for far distance vision with high magnification and a second configuration for intermediate and near distances with wider field of view, allowing the system to adapt its parameters dynamically rather than being fixed
2Measurement precision
If conventional binoculars are used for far distance vision, then far distance viewing is improved, but binocular vision capability is lost at intermediate and near distances due to separate non-overlapping fields of view
Solution Approach 1:
The patent creates a universal binocular system that functions effectively at multiple distance ranges (far, intermediate, and near distances) by providing two different optical configurations. The device can operate as a high-magnification far-distance binocular or switch to a wider-field intermediate/near-distance binocular mode, making it versatile across different viewing scenarios rather than specialized for only one distance range
3Measurement precision
If the field of view for each optical channel is reduced for high magnification, then magnification is improved, but overlapping of fields of view is reduced or lost
Solution Approach 1:
The system dynamically adjusts the relative positioning and optical parameters of the two channels based on the selected operating mode. In far-distance mode, the channels are configured with narrow, overlapping fields of view optimized for high magnification. When switching to intermediate or near-distance mode, the system reconfigures the channels to provide wider fields of view with appropriate overlap, ensuring reliable binocular vision at each distance range

AI summary
The present disclosure relates to a see-through binocular device for far, intermediate and near distances. This includes two see-through optical modules with each see-through optical module configured for projecting without inversion an image of an object on a first plane. Each see-through optical module includes an optical element with variable optical power an optical projection system configured for projecting the optical element with variable optical power on a second plane. This includes the input optical axes of the two see-through optical modules which intersect at a plane corresponding to a near distance, such that their fields of view overlap completely or almost completely for viewing objects located at a near distance. The disclosure also relates to a system and method for determining sensory eye dominance and/or for determining sensory eye dominance strength.
