中文摘要：
基于脉搏图像传感器工作原理，利用Abaqus软件建立传感器有限元模型。应用Abaqus／Explicit对模型进行动态分析，分析传感器薄膜上不同位置点的竖向位移，分别获取了脉搏波形；对脉搏信号进行时域分析，提取脉搏时域特征参数，为进一步研究薄膜三维动态变化奠定了基础。
英文摘要：
Based on the working principle of pulse image sensor, the finite element model of pulse image sensor is established by the software Abaqus. The Abaqus/Explicit is used to make the dynamic analysis of the model. By application of Abaqus/Explicit dynamic analysis of the model, the pulse waveform of the different points on the film is extracted. Through the analysis of the displacements of the different points. Based on the analysis of the pulse signal in time domain, the characteristic parameters of the pulse signal in time domain are extracted. On the basis of this research,further research on the thin film 3D dynamic changes can be made.
