Radiation Detector

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a novel radiation detector array composed of multiple conversion units, each with a radiation-responsive element and a capacitor formed by an insulator. All conversion units share a common electrolytic layer as the insulator, which electrically couples them and enables intrinsic crosstalk between units. This design allows built-in pre-processing functions such as edge and motion detection directly at the detector hardware level, mimicking aspects of biological vision systems.

Use CasesContent extracted from patent full text and abstract with AI.

• Medical imaging devices for enhanced real-time image analysis (e.g., X-ray, CT, PET, MRI detectors).
• Industrial machine vision systems requiring rapid identification of edges, defects, or movement.
• Security and surveillance cameras with built-in edge and motion detection to reduce false alarms and data throughput.
• Autonomous vehicle sensors and driver-assistance systems that benefit from fast, energy-efficient pre-processing of visual information.
• Environmental monitoring detectors tracking radiation, UV, IR, or other spectra with intelligent filtering.
• Flexible and low-cost imaging arrays for wearable and portable devices.
• Scientific research tools requiring multi-spectral image detection or analysis.

BenefitsContent extracted from patent full text and abstract with AI.

• Enables hardware-level edge and motion detection, reducing the need for extensive digital post-processing and speeding up image acquisition and analysis.
• Reduces power consumption and data bandwidth by only transferring relevant, pre-processed signals for further processing.
• Simplifies detector fabrication using a shared layer and offers potential for low-cost, flexible, and biodegradable designs (including organic/bio materials).
• Allows multi-spectral (visible, UV, IR) detection and layered architectures without additional filters or increased dead space.
• Intrinsic crosstalk improves image contrast and sharpness at the hardware level, similar to pre-processing by the biological eye.
• Supports energy-efficient operation with passive detection modes, which is crucial for portable or battery-powered applications.
• Highly tunable for different application needs (e.g., wavelength range, detection sensitivity, speed).
