Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an additional sensor is added to detect exposure dose, then the exposure dose detection capability is improved, but the system cost and system volume increase
Solution Approach 1:
The detection panel is designed to perform multiple functions: it detects both the exposure dose (through first pixels in a first region) and generates data images (through second pixels in a second region). This multi-functionality eliminates the need for separate dedicated sensors, thereby reducing system cost and volume while maintaining exposure dose detection capability
Solution Approach 2:
The detection panel is segmented into different regions (first region with first pixels and second region with second pixels) that serve different purposes. The first region is used for exposure dose detection while the second region is used for data image generation. This segmentation allows the system to use existing detection panel resources for dose detection without adding external sensors

Function Achieved in This Case
Enables exposure dose detection without additional sensors, reducing system cost and volume while generating accurate data images by compensating for visual discontinuities.
Implementation Method 1
The detection panel converts an input light from the light source device into a converted light and converts the converted light into a charge
Data Source
AI summary
The disclosure provides a light detection device and a detection method for controlling a light source device. The light detection device includes a detection panel and a processor. The detection panel converts an input light from the light source device into a converted light and converts the converted light into a charge. The processor selects a first region and a second region other than the first region from the detection panel. A first charge of the converted light received by at least one first pixel of the first region during a first period is used to detect a dose of the input light. A second charge of the converted light received by the second region during the first period is used to generate a data image. The charge of the converted light received by at least one first pixel during a second period is used to generate the data image.
