Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Infrared radiation detectors, such as microbolometers, can become over-saturated and unreliable when exposed to high-intensity sources like solar radiation, leading to physical modifications and digital artifacts in images.
Innovation Solution
A system comprising a processing unit and a modifiable medium, such as an array of reflecting or transmissive devices, or a variable-position occulting disk, that modifies its configuration based on exposure data to prevent excessive radiation from reaching the detector, using address data to reposition or block radiation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the microbolometer is exposed to solar radiation or high-intensity radiation sources, then the detector can capture a broader range of radiation sources, but the pixels may become over-saturated and suffer physical modifications that render them unreliable
Solution Approach 1:
The patent applies preliminary action by calculating the solar position and predicting which pixels will be exposed to high-intensity radiation before the exposure occurs. The system pre-identifies at-risk pixels using navigation data and solar position algorithms, then proactively blocks radiation to those specific pixels before over-saturation can occur, preventing the harmful effect rather than reacting to it afterward.
Solution Approach 2:
The patent introduces an intermediary element - a modifiable medium such as an array of reflecting devices, transmissive devices, or an occulting disk - that acts as a mediator between the solar radiation and the microbolometer pixels. This intermediary can be dynamically reconfigured to block radiation from specific pixels that are predicted to be over-exposed, while allowing other pixels to continue capturing radiation normally, thus protecting pixel reliability without compromising overall detection capability.
2Quantity of substance
If the pixel maximum exposure limit is exceeded, then the pixel may capture more radiation information, but the pixel suffers physical modification that alters electrical properties and induces digital artifacts
Solution Approach 1:
The patent applies preliminary anti-action by implementing a feedback mechanism that monitors pixel exposure levels and actively counteracts over-exposure before it causes physical damage. The system calculates which pixels will exceed their maximum exposure limits, then uses the modifiable medium to block radiation from those specific pixels in real-time, preventing the accumulation of excessive radiation energy that would otherwise cause physical modifications and digital artifacts.
Solution Approach 2:
The patent implements feedback by continuously monitoring exposure data from the microbolometer, comparing it against maximum exposure limits, and using this information to dynamically reconfigure the modifiable medium. The system processes exposure data, identifies pixels exceeding or likely to exceed their limits, and adjusts the reflecting or transmissive devices accordingly, creating a closed-loop control system that prevents over-exposure and the resulting harmful artifacts.
3Reliability
If a modifiable medium is introduced to block radiation from specific pixels, then pixel reliability is maintained, but the device complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the radiation control function into pixel-specific or region-specific adjustments rather than blocking all radiation uniformly. The modifiable medium consists of arrays of individually controllable reflecting or transmissive devices that can be adjusted independently for different spatial regions, allowing selective protection of only those pixels at risk while maintaining simplicity for the rest of the system.
Solution Approach 2:
The patent applies self-service by implementing an automated control system that uses navigation data and solar position calculations to autonomously determine which pixels need protection and dynamically reconfigures the modifiable medium without requiring manual intervention. The processing unit automatically processes exposure data, generates control signals, and adjusts the reflecting or transmissive devices based on real-time conditions, reducing operational complexity despite the added hardware.

AI summary
Present novel and non-trivial system, device, and method for preventing artifacts in an electromagnetic imaging system are disclosed. A processing unit may be configured to receive or derive exposure data corresponding to an exposure of electromagnetic radiation; identify each cell of the exposure data exceeding a maximum exposure limit; generate address data representative of an address of each identified cell; and send the address data to a modifiable medium such as (1) an array of reflecting devices that are modifiable through repositioning techniques, (2) an array of transmissive devices that are modifiable to prevent the passage of radiation, and/or (3) an occulting disk whose position is modifiable to prevent the passage of radiation. The exposure data could be comprised of actual exposure data received from a radiation detector. Alternatively, the exposure data could be comprised of calculated exposure data.
