Speckle reduction using the discrete Fourier filtering technique
We present a digital signal processing technique that reduces the speckle content in reconstructed digital holograms. The method is based on sequential sampling of the discrete Fourier transform of the reconstructed image field. The resulting images show a reduction in speckle.
