Method and system for matching calibrations of detectors in a detector array

A system for checking a gauge response comprising:

• a radiation source;
• a detector array linearly arranged in a first direction;
• a sample holder;
• a space between the source and the detector array;
• and
• a computing device having executable code stored thereon, wherein the executable code is configured to send instructions for one or more of:
• positioning, one at a time, one or more samples with known profiles and uniform compositions that are in the sample holder, in one or more positions between the radiation source and a subset of detectors in the array of detectors;
• generating sample signals by irradiating the samples with radiation from the radiation source and detecting radiation transmitted through the samples and to the subset of detectors;
• inputting the sample signals into calibration curves for each of the subset of detectors and each of the one or more samples, thereby determining values corresponding to each of the one or more samples and each of the subset of detectors;
• and
• providing a first indication if the values corresponding to the one or more samples are consistent with known profiles and uniform compositions of the samples.
