Observation Device Optical Channel Separation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing observation devices face a challenge in providing clear and distinct additional information while maintaining low energy consumption, as energy-saving displays often result in low brightness and contrast, making it difficult to recognize information when superposed with the day vision image.
Innovation Solution
A combination optical system with two zones is used to separate the day vision and information channels, allowing a low-energy display to provide clear information in one region without superposition with the day vision image, while enabling superposition in another region for enhanced visibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If an energy-saving display is used, then energy consumption is reduced, but brightness and contrast are reduced making information difficult to recognize when superposed with day vision image
Solution Approach 1:
The display channel is divided into two separate displays: a first display optimized for energy efficiency and a second display optimized for brightness and contrast. This segmentation allows each display to perform its specialized function, with the first display handling information that doesn't require high visibility and the second display providing high-visibility information when needed.
Solution Approach 2:
The system dynamically switches between different display configurations based on operational needs. The second high-brightness display can be activated selectively when information clarity is critical, while the first energy-saving display operates continuously for basic information display, creating a dynamic balance between energy consumption and visibility requirements.
2Illumination intensity
If two different displays are used, then clear information display is achieved, but device complexity and cost increase
Solution Approach 1:
Both displays are integrated into a single unified display channel that shares common optical pathways and control systems. The beam splitter and optical combiner serve both displays simultaneously, allowing the system to achieve enhanced information display capability while minimizing additional optical complexity through shared components.
3Illumination intensity
If two different displays are used, then information visibility is improved, but energy consumption increases reducing operating time
Solution Approach 1:
The second high-brightness display operates periodically or on-demand rather than continuously, activating only when information clarity is critical. This periodic operation allows the system to maintain high information visibility when needed while minimizing overall energy consumption during normal operation, thereby extending battery operating time.

AI summary
An observation device includes at least one day vision channel, an information channel with a graphic electronic display for producing a display image and a combination optical system for combining the day vision channel and the information channel, so that a combined overall image forms.
