Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing imaging systems face a trade-off between focal length and field angle, limiting the ability to obtain enlarged optical information in a wide range simultaneously.
Innovation Solution
An optical device with an imaging optical system, optical elements, and a prism that guides light with a different principal ray angle to form images in a specified area, allowing for both enlarged and wide-range optical information capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the focal length is increased to obtain enlarged optical information, then the field angle becomes narrower
Solution Approach 1:
The optical system is divided into multiple optical systems with different focal lengths. Each optical system captures images of the same subject at different magnifications, allowing the system to obtain both enlarged optical information and wide field angle coverage by combining images from multiple segmented optical paths
Solution Approach 2:
The imaging device is designed to perform multiple functions simultaneously: it captures images with both long focal length (for enlargement) and short focal length (for wide angle) using a single integrated system that includes multiple optical systems, thereby achieving both measurement precision and adaptability
2Adaptability or versatility
If the field angle is widened to capture a wider range, then the focal length becomes shorter reducing image enlargement
Solution Approach 1:
The optical system is divided into multiple optical systems with different focal lengths. Each optical system captures images of the same subject at different magnifications, allowing the system to obtain both enlarged optical information and wide field angle coverage by combining images from multiple segmented optical paths
Solution Approach 2:
Images captured by multiple optical systems with different focal lengths are merged or superimposed on the same imaging element, combining the advantages of both wide-angle and telephoto views into a single integrated output that provides both wide range coverage and enlarged detail
