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.
