Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current X-ray optical systems, such as Wolter I telescopes, face challenges in producing large diameter optics with high precision and resolution, requiring expensive and complex manufacturing processes, and suffer from a small field of view and dead zones that reduce their effectiveness.
Innovation Solution
The proposed X-ray optical system uses a geometric layout of thin, rotationally symmetric modules with square apertures and filling dead zones with parabolic or elliptic foils, allowing for efficient aperture utilization and elimination of dead zones, using commercially available substrates and enabling rotation for increased band homogeneity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If Wolter I telescope design with parabolic andhyperbolic mirrors is used, then X-ray focusing capability is improved, but manufacturing complexity and cost increase significantly
Solution Approach 1:
The optical system is divided into multiple identical modules, each containing simplified optical elements. Instead of manufacturing one complex Wolter I telescope, the system uses many identical modular units with planar or cylindrical mirrors, reducing individual manufacturing complexity while achieving collective focusing capability through geometric arrangement.
Solution Approach 2:
The patent uses identical replicated modules throughout the optical system. Each module is a copy of the others, allowing standardized manufacturing processes and simplifying production. The complex Wolter I geometry is replaced by copying simpler modular units in large numbers to achieve the desired optical performance.
2Manufacturing precision
If large diameter mirrors are manufactured using polishing technology, then optical precision is improved, but production time and cost increase
Solution Approach 1:
Large mirrors are divided into many smaller mirror segments arranged in modular units. Each small mirror can be manufactured quickly using simple processes, and the collective array achieves the effective aperture of a large mirror without requiring polishing of a single large surface.
Solution Approach 2:
The patent employs inexpensive, simple-to-manufacture mirror substrates that do not require expensive polishing. These simpler optical elements are used in large numbers, trading individual component simplicity for system-level performance, thereby reducing both manufacturing cost and time.
3Ease of manufacture
If replication technology is used for smaller diameter mirrors, then manufacturing cost is reduced, but mandrel manufacturing complexity increases
Solution Approach 1:
The patent extracts the complex mandrel manufacturing requirement from the process by using simple planar or cylindrical substrates instead of complex rotationally symmetric mandrels. The optical performance is achieved through the geometric arrangement of many simple elements rather than through complex individual component shaping.
4Measurement precision
If X-ray optical system uses traditional Wolter I design, then focusing resolution is improved, but field of view remains limited
Solution Approach 1:
The patent transitions from the traditional two-dimensional Wolter I mirror surface to a three-dimensional array of modular units distributed in space. This dimensional expansion allows the system to capture X-rays from a wider angular range while maintaining focusing capability through the collective geometry of the modular arrangement.

AI summary
X-ray optical system composed of modules wit thin reflection foils or rectangular small channels. The optical system (3) is composed of minimum 5 segments (2), each segment (2) is assembled from minimum one module (1) and the diagonals of all modules (1) in a segment (2) are always in parallel with the symmetry axis (5) of the segment (2) and the segment (2) is a sector with a central angle from 18° to 72°, in the narrowest part of which is the dysfunctional or "dead"z one (6). The X-ray optical system has this dead zone (6), which can be filled with thin, rotationally symmetric foils (7), laid out in another geometric layout so that a common focus of the whole optical system (3) is formed. The X-ray optical system (3) has individual segments (2) laid out so that the aperture of the X-ray optical system (3) approaches the circular aperture and the symmetry axis (5) of a segment (2) always intersects the optical axis (4) of the optical system (3).
