ISO/TR 11146-3:2004规定了支持ISO 11146-1的激光束的束宽（直径）、发散角和光束传输比的测量方法。它提供了基于维格纳分布二阶矩的激光束特性的理论描述，包括几何和固有光束特性，并提供了适用于CCD相机等矩阵探测器的适当背景减除方法的重要细节。它还提出了用于表征柱头或简单像散光束的替代方法，适用于矩阵检测器不可用或提供不满意结果的情况。

ISO/TR 11146-3:2004 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.
