Paper Abstract

We propose a novel method for speckle reduction based on angular compounding by B-scan Doppler shift encoding (ACBD). By de-centering the beam from the pivot of a scanning mirror, the illumination angle can be encoded by Doppler shift detected by B-scan analysis. Compounding multiple images reconstructed from different Doppler-shift bands, we can suppress speckle without sacrificing image acquisition speed. Speckle reduction with ACBD is demonstrated by imaging a phantom and a living avian embryo
