X-ray Optic Alignment with Four-Sector Sensor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current x-ray optical systems require periodic offline alignment of optics, which is inefficient and disrupts operations, as they lack automated alignment capabilities that can integrate beam collimation and monitoring.
Innovation Solution
An automated alignment system incorporating an x-ray source, optic, collimation element, and alignment sensors that generate signals to determine system alignment, allowing for real-time adjustments using a controller, with sensors placed radially on the collimation element and a beam stopper for intensity measurement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If periodic offline alignment is performed, then alignment accuracy is maintained, but system downtime increases and productivity decreases
Solution Approach 1:
The patent implements continuous alignment monitoring during normal system operation using sensors that detect the position of the x-ray beam relative to the optic. This allows the alignment function to operate continuously rather than periodically, eliminating downtime while maintaining measurement precision through real-time feedback
Solution Approach 2:
The system employs feedback mechanisms where sensors continuously monitor beam position and provide signals to a controller that adjusts the optic position accordingly. This closed-loop feedback enables real-time alignment correction during operation, resolving the contradiction between maintaining accuracy and avoiding downtime
2Productivity
If automated alignment monitoring is added, then productivity improves through continuous operation, but device complexity increases
Solution Approach 1:
The patent integrates alignment monitoring functions into existing system components, allowing sensors and controllers to serve dual purposes: normal system operation and alignment monitoring. This multi-functionality approach improves productivity while minimizing the addition of separate dedicated alignment equipment
Solution Approach 2:
The system implements self-aligning capabilities where the automated monitoring and adjustment mechanisms enable the system to correct its own alignment issues without external intervention. This self-service approach reduces the need for complex external alignment equipment and manual procedures

Data Source
AI summary
A system for x-ray optical alignment. The system includes an x-ray source, an optic, a collimation element, and alignment sensors. The x-ray source generates an x-ray beam that is directed by the optic at a sample. The collimation element is located between the optic and the sample to define the profile of the x-ray beam. The sensors receive the x-ray beam from the optic and generated signal indicative of the system alignment. The sensors may be located on a surface of the collimation element facing the optic. The inner edge of the sensors may be located at equal intervals radially about the collimation element and may form an aperture having a symmetric shape.
