ISO/TR 11146-3:2004 Lasers and laser-related equipment - Test methods for laser beam widths, divergence angles and beam propagation ratios - Part 3: Intrinsic and geometrical laser beam classification, propagation and details of test methods
This part of ISO 11146 specifies methods for measuring beam widths (diameter), divergence angles and
beam propagation ratios of laser beams in support of ISO 11146-1. It provides the theoretical description of
laser beam characterization based on the second-order moments of the Wigner distribution, including
geometrical and intrinsic beam characterization, and offers important details for proper background
subtraction methods recommendable for matrix detectors such as CCD cameras. It also presents alternative
methods for the characterization of stigmatic or simple astigmatic beams that are applicable where matrix
detectors are unavailable or deliver unsatisfying results.
