文摘
A fast method of geometric calibration of detectors is described. The main idea of this method is to determine offsets by fitting real data using a set of analytical functions which describe the displacement of one detector relative to another. This method can be applied to determine the offset of one detector relative to another detector or one part of the detector relative to its other part. The form of the analytical functions depends on the geometry of the experiment and on the directions of the coordinate axes. The analytical functions are obtained using the rotation matrices.
