基本为球形的多层结构的非破坏性和无接触的表征方法及相关装置
摘要：
本发明涉及一种用于多层结构（1）的非破坏性和无接触的表征方法，多层结构（1）具有基本上的球形并包括由分界面分开的至少两层（2、3、4、5、6），该方法包括以下步骤：利用激光（11）在热弹性状态下局部地加热结构（1），使得结构（1）以非破坏性方式振动；测量结构（1）的振动模式的共振频率（Fexp）；由结构（1）的共振频率（Fexp）导出关于结构（1）的完整性、或形状或机械特征的至少一个特征。
摘要（英）：

The invention relates to a method for the non-destructive and contactless characterisation of a multilayered structure (1) having a substantially spherical shape and including at least two layers (2, 3, 4, 5, 6) separated by interfaces, said method including the following steps: using a laser (11) for locally heating the structure (1) in a thermoelastic state so that the structure (1) is vibrated in a non-destructive manner; measuring the resonance frequencies (Fexp) of the vibration modes of the structure (1); deriving at least one characteristic concerning the integrity or the shape or the mechanical behaviour of the structure (1) from the resonance frequencies (Fexp) of the structure (1).
