太赫兹波与不同的介质相互作用，探测器在不同的时间节点检测到携带介质信息的太赫兹时域波形，分析不同时域波形峰值点的飞行时间差，分别建立了透射式和反射式太赫兹无损检测单点厚度提取模型。在柔性装配过程中，一般有机硅胶的折射率难以提取，基于单点厚度提取模型，绘制了胶层空间分布三维形貌图，并提出了采用厚度均匀性标准偏差的方法评价胶层空间分布离散性。太赫兹时域光谱技术系统分析胶层厚度的均匀性，检测精度可达100μm，对保证胶层连接强度有重要意义。

When THz waves interact with different media,detector detects the THz time-domain waveform of carrying media information at different time nodes,the flight time difference between the THz pulses is analyzed,extraction model of transmission and reflection THz nondestructive inspection of single point thickness are established respective-ly. In flexible assembly process,refractive index of silicone adhesive is difficult to be extracted. Based on the single-point thickness extracting model,a three-dimensional topography of adhesive spatial distribution is drawn,and the standard deviation for thickness uniformity is put forward to evaluate the discreteness of adhesive spatial distribution.Analyzing the uniformity of adhesive thickness using THz-TDS system,the detecting accuracy is up to 100 μm,and it is important for ensuring the adhesive connection strength.
