Medical Microscope Eyepiece Layout for Natural 3D Viewing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 3D digital microscopes for medical diagnosis and treatment fail to provide a natural stereoscopic image, as observers view images captured rather than directly through a lens, lacking a suitable design to replicate direct observation.
Innovation Solution
A microscope design with dual objective and eyepiece optical systems forming a convergence angle, combined with specific pixel and angle of view parameters, allows for a natural stereoscopic image display through a display element and eyepiece optical system, ensuring minimal distortion and comfortable viewing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a 3D digital microscope is used to capture and display images, then the device complexity is reduced and operational freedom is improved, but the natural steresoscopic image quality deteriorates compared to direct optical observation
Solution Approach 1:
The patent applies parameter changes by carefully selecting and optimizing the pixel count of the display element (2000-4000 horizontal or vertical pixels) and the angle of view of the eyepiece optical system (35-60 degrees). These parameter adjustments ensure that the displayed image maintains natural stereoscopic perception comparable to direct optical observation, resolving the contradiction between digital operation freedom and image quality.
Solution Approach 2:
The patent creates a faithful optical copy of the direct observation experience through the eyepiece optical system. The eyepiece directs light from the display element to the observer's eye, replicating the natural stereoscopic image formation that would occur with direct optical observation, thereby maintaining image quality while enabling digital operation benefits.
2Measurement precision
If the display element has high pixel count and appropriate angle of view, then natural steresoscopic image quality is achieved, but the device complexity increases
Solution Approach 1:
The patent merges the display element and eyepiece optical system into an integrated observation path. The eyepiece optical system directly receives light from the display element and directs it to the observer's eye, combining digital display capabilities with optical observation in a unified system. This integration achieves natural stereoscopic image quality without requiring separate complex subsystems.
3Measurement precision
If dual objective and eyepiece optical systems with convergence angle are used, then natural steresoscopic image is achieved, but the device complexity increases
Solution Approach 1:
The patent segments the optical system into distinct functional modules: a first objective optical system for capturing the subject image, a second objective optical system for capturing the reference image, and an eyepiece optical system for directing light to the observer. Each module is optimized independently, allowing the convergence angle between objective systems to be set for natural stereoscopic effect while managing overall system complexity through modular design.
