Material Identification Spectral Analysis Two-Phase Estimation

The patent divides the spectral analysis into two phases: a first phase that performs a preliminary material identification using a restricted common energy band to reduce complexity, and a second phase that performs a refined identification using a wider energy band for improved reliability. This segmentation allows the system to balance computational complexity with identification accuracy by processing materials through different analysis depths.

The patent implements a preliminary selection step before the final material identification. In the first phase, the system quickly narrows down candidate materials using a restricted energy band, then uses this preliminary result to guide the second phase analysis. This preliminary action reduces the computational burden of the subsequent detailed analysis while maintaining high reliability through the two-phase approach.

The patent segments the spectral comparison process into two distinct phases with different energy band scopes. The first phase uses a restricted common energy band for quick preliminary identification, while the second phase expands to a wider energy band for precise final identification. This segmentation enables the system to achieve high measurement precision without proportionally increasing processing time, as the majority of quick filtering is done in the first phase.

The first phase serves as a preliminary filtering step that quickly eliminates non-matching materials using a restricted energy band. This preliminary action reduces the number of candidates that require the computationally intensive second phase analysis with the wider energy band, thereby maintaining high precision while controlling overall processing time.

The patent implements a two-phase estimation process that segments the material identification workflow. The first phase performs a rapid preliminary estimation using a restricted energy band to quickly identify candidate materials. The second phase then performs a more detailed estimation on the narrowed-down candidate set using a wider energy band. This segmentation dramatically improves identification speed by avoiding the computationally intensive task of comparing all reference materials in a single step.

The first phase acts as a preliminary filtering mechanism that quickly reduces the search space of reference materials. By performing this preliminary estimation before the second phase, the system avoids the time-consuming operation of directly comparing spectral coefficients across all reference materials, thereby achieving high productivity while managing complexity through the structured two-phase approach.

The patent segments the spectral measurement and analysis into two phases with different precision requirements. The first phase uses a restricted energy band where lower measurement precision is acceptable, allowing faster acquisition with less photon collection time. The second phase applies higher precision measurement only to the narrowed-down candidate materials using a wider energy band. This segmentation reduces overall measurement time while maintaining sufficient precision for accurate material identification.

The first phase performs a preliminary spectral analysis with relaxed precision requirements, allowing the system to quickly process measurements with shorter acquisition times and fewer photons. This preliminary measurement filters out clearly non-matching materials before the second phase performs high-precision measurements on candidates. This approach reduces the total measurement time and photon loss while maintaining adequate precision through the two-stage process.
