| 摘要 |
A method and an apparatus for increasing accuracy of a spectrometer system is provided. The method comprises correcting for, quality of light source, exposure time, distortion in y direction, distortion in x direction, temperature dependence, variability of for pixel alignment, dark pixels, bad pixels, pixel read noise, pixel dark current noise, and a combination thereof, in a spectrometer system, to produce an algorithm for optimizing of spectral data, and measuring a sample within the spectrometer system using the algorithm for optimizing spectral data. The apparatus comprises a spectrometer system comprising, a composite external light source in optical communication with, and in optical sequence with, a source light collector, an illumination light structuring component, a sample, a sample light collector, a spectrometer light structuring component, a light dispersing engine, and one or more photo detectors, and electrical signal converter, the electrical signal convertor in communication with a data preprocessing unit, and a data analyzer, the spectrometer system further comprising one or more of corrected photo detector algorithm, a sample illumination correction algorithm, an LDE-PD alignment procedure, SLSC- LDE alignment procedure, a distortion correction matrix, an algorithm for optimizing of spectral data, or a combination thereof. |
