- Image Sensor Technology
Background:
- Image sensors, particularly Charge-Coupled Devices (CCDs), are susceptible to blooming overload and image lag.
- These artifacts degrade image quality, especially in high-light conditions.
Purpose of the Study:
- To present the design and operational principles of a new antiblooming array.
- To demonstrate a method for mitigating blooming and image lag in CCD-based imaging systems.
Main Methods:
- Development of a 120x100 pixel array.
- Integration of hydrogenated amorphous silicon photoconductors with ferroelectric liquid-crystal shutters in each cell.
- Coupling the array with a CCD camera.
Main Results:
- The array effectively suppresses blooming overload.
- The device significantly reduces image lag.
- Successful integration with a CCD camera was achieved.
Conclusions:
- The described antiblooming array is a viable solution for enhancing image quality in CCD cameras.
- This technology offers improved performance in challenging lighting scenarios by preventing common imaging artifacts.
