Transparent Film Protects Imaging Sensor Surface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional solid state imaging elements for pathological diagnosis are prone to damage when used with multiple specimens, leading to decreased image accuracy due to direct contact and potential stress on the light receiving surface.
Innovation Solution
An electronic prepared slide assembly method that interposes a nonvolatile transparent member, such as a transparent film or oil layer, between the solid state imaging element and the specimen, preventing direct contact and damage while maintaining high image accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the specimen is placed directly on the light receiving surface of the solid state imaging element, then the observation apparatus can be simplified and cost reduced, but the light receiving surface may be damaged and image accuracy decreases
Solution Approach 1:
A transparent member is introduced as an intermediary between the specimen and the light receiving surface of the solid state imaging element. This transparent member allows light to pass through while preventing direct contact between the specimen and the imaging element, thereby protecting the light receiving surface from damage during repeated use.
2Productivity
If the solid state imaging element is attached to the specimen each time the specimen is replaced, then multiple specimens can be imaged using one imaging element, but the damage on the light receiving surface progresses and image accuracy decreases
Solution Approach 1:
The transparent member serves as a protective intermediary that remains on the light receiving surface during specimen replacement. This allows multiple specimens to be imaged using the same solid state imaging element without progressive damage to the light receiving surface, maintaining image accuracy across multiple uses.
Solution Approach 2:
The transparent member is disposed on the light receiving surface in advance before specimen placement. This preliminary protective measure ensures that the light receiving surface is already protected when the specimen is placed, preventing damage from the outset and enabling repeated imaging cycles.
3Reliability
If a transparent member is interposed between the light receiving surface and the specimen, then the solid state imaging element is protected from damage, but the apparatus structure becomes more complex
Solution Approach 1:
The transparent member is implemented as a thin film or membrane structure that can be disposed on the light receiving surface. This thin film approach provides effective protection against damage while minimizing the increase in structural complexity and maintaining optical transparency for high-quality imaging.

Function Achieved in This Case
This configuration allows for high-image accuracy pathological diagnosis at a low cost by protecting the imaging element and extending its usage across multiple specimens without degrading the light receiving surface.
Implementation Method 1
a transparent member that is removable and nonvolatile and is disposed on the light receiving surface to seal the light receiving surface
Data Source
AI summary
An electronic prepared slide includes: an image sensor that has a light receiving surface and receives, on the light receiving surface, light that has passed through a specimen disposed above the light receiving surface; and a removable nonvolatile transparent film that is disposed on the light receiving surface and seals the light receiving surface.
