前言

本文件按照GB/T1.1—2020《标准化工作导则第1部分：标准化文件的结构和起草规则》的规

定起草。

本文件修改采用ISO23701：2023《光学和光子学激光器和激光相关设备激光光学元件吸收测

量和成像的光热技术》。

本文件与ISO23701：2023相比做了下述结构调整：

—第5章对应ISO23701：2023的5.1；

—第6章对应ISO23701：2023的5.2；

—第7章对应ISO23701：2023的5.3；

—第8章对应ISO23701：2023第6章；

—第9章对应ISO23701：2023第7章；

—第10章对应ISO23701：2023第8章；

—附录A对应ISO23701：2023附录B；

—附录B对应ISO23701：2023附录A。

本文件与ISO23701：2023的技术差异及其原因如下：

—用规范性引用的GB/T15313代替了ISO11145（见第3章），以适应我国的技术条件；

—用规范性引用的GB/T25915.1—2021代替了ISO14644﹘l（见7.1），以适应我国的技术

条件；

—删除了ISO23701：2023中6.4附录B的引用，附录B给出的是表面吸收与体吸收的分离，并没

有直接给出三维吸收分布扫描测量中深度方向测量时的标定程序。

本文件做了下列编辑性改动：

—将标准名称改为《激光器和激光相关设备激光光学元件吸收分布测量方法光热成像法》，

与现有标准协调。

请注意本文件的某些内容可能涉及专利。本文件的发布机构不承担识别专利的责任。

本文件由中国机械工业联合会提出。

本文件由全国光学和光子学标准化技术委员会（SAC/TC103）归口。
