适用范围：This part of ISO 11146 specifies methods for measuring beam widths (diameter), divergence angles andbeam propagation ratios of laser beams in support of ISO 11146-1. It provides the theoretical description oflaser beam characterization based on the second-order moments of the Wigner distribution, includinggeometrical and intrinsic beam characterization, and offers important details for proper backgroundsubtraction methods recommendable for matrix detectors such as CCD cameras. It also presents alternativemethods for the characterization of stigmatic or simple astigmatic beams that are applicable where matrixdetectors are unavailable or deliver unsatisfying results.
