1Measurement precision
If the number of detectors is increased to improve resolution, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The patent creates virtual measurement data by copying and transforming actual measurement data through mathematical operations. Virtual measurement data is generated by applying transformation matrices and interpolation methods to the actual detector readings, effectively creating a higher-resolution representation without adding physical detectors. This allows the system to achieve super-resolution through computational copying rather than hardware expansion.
Solution Approach 2:
The patent replaces the mechanical approach of increasing detector count with a computational method. Instead of physically adding more detectors to capture higher resolution data, the system uses algorithms including super-resolution reconstruction, interpolation, and data fusion to computationally enhance the resolution. This substitution of mechanical hardware expansion with software-based processing enables improved measurement precision without increasing device complexity.
2Measurement precision
If super resolution is applied to improve measurement accuracy, then measurement precision is improved, but computational complexity increases
Solution Approach 1:
The patent performs preliminary actions by pre-processing the actual measurement data to create virtual measurement data before the main super-resolution reconstruction. This involves generating transformed versions of the data through interpolation and applying transformation matrices in advance. By preparing multiple virtual datasets beforehand, the computational burden during the final reconstruction step is reduced, as the system only needs to fuse these pre-prepared virtual datasets rather than processing raw data from scratch.
Solution Approach 2:
The patent segments the super-resolution process into distinct stages: (1) generating virtual measurement data from actual data through transformation, (2) fusing multiple virtual datasets, and (3) reconstructing the final super-resolution spectrum. This segmentation allows each stage to be optimized independently and reduces overall computational complexity by breaking down the complex reconstruction task into manageable steps. The virtual measurement data serves as an intermediate representation that simplifies the final reconstruction process.
