Filter arrays
| DWPI Title: Scintillator apparatus used for detecting neutrons, has filter array which has first filters configured to filter photons with wavelengths outside of first wavelength band, buffer layer which is located between scintillator and filter array |
| Abstract: The various technologies presented herein relate to a tiled filter array that can be used in connection with performance of spatial sampling of optical signals. The filter array comprises filter tiles, wherein a first plurality of filter tiles are formed from a first material, the first material being configured such that only photons having wavelengths in a first wavelength band pass therethrough. A second plurality of filter tiles is formed from a second material, the second material being configured such that only photons having wavelengths in a second wavelength band pass therethrough. The first plurality of filter tiles and the second plurality of filter tiles can be interspersed to form the filter array comprising an alternating arrangement of first filter tiles and second filter tiles. |
| Use: Scintillator apparatus used for detecting neutrons. |
| Advantage: Reduces error and equally applies bias to photometry technologies, and improves photometric accuracy during sampling by the application of spatial sampling. |
| Novelty: The apparatus (100) has a filter array (120) which has first filters configured to filter photons having wavelengths outside of a first wavelength band. The second filters filter photons having wavelengths outside of a second wavelength band, in which the first filters and the second filters are co-located as tiles forming the filter array. The filters in the first filters are attached to a first detector in the detectors (130), and the filters in the second filters are attached to a second detector in the detectors. A buffer layer is located between the scintillator and the filter array. |
