An improved deconvolution beamforming algorithm based on fiber optic microphone array for acoustic imaging
An improved deconvolution beamforming algorithm has been proposed to achieve imaging localization using fiber optic microphone arrays. The method accelerates the solution of the deconvolution approach for the mapping of acoustic sources 2 (DAMAS2) by introducing a fast iterative shrinkage-thresholding algorithm (FISTA), and optimizes the point spread function (PSF) combined with regularized filtering to improve the imaging resolution. Experimental results demonstrate that the method takes only 3.799 seconds for 200 iterations, which can significantly reduce the runtime while improving the imaging resolution.
