Study on the Wrapping Error of GREEN’s Function Sampled in K Space

Abstract:

During the near-field acoustic holographic reconstruction with sampling GREEN’s function in k space, there will be aliasing which results in the wrapping error for the infinite extension of GREEN’s function in real space. The magnitude of wrapping error lies on the decrement of GREEN’s function in real space. The paper applies a 2-D low-pass filter to remove the hyper space element in order to reduce the wrapping error. The simulation indicates that the method can reduce the wrapping error in the holographic reconstruction efficiently.
