The Discrete Error Analysis of GREENs Function Sampled in Real Space

摘要：

　　During the near-field acoustic holographic reconstruction,there will be error which make the reconstruction uncertain in sampling GREENs function in real space.The magnitude of discrete error lies on the size of sampling interval and the change rate of GREENs function.The longer interval,the greater error.The faster change rate,the greater error.Because the GREENs function is sensitive to the reconstruction distance and the reconstruction frequency and change with direct ratio and inverse ratio,the discrete error is with direct ratio to the reconstruction frequency and with inverse ratio the reconstruction distance.
