Abstract
In this study we have exploited the parallel nature of the computations involved in the process of numerical volume reconstruction of three-dimensional digital holographic microscopy and utilized CUDA enabled graphics processing unit (GPU) to accelerate the reconstruction process. We have recorded holograms of the 3D specimen using CCD with inline setup, then using GPU we have initiated CUDA kernels for de-convolution of the diffraction integral for multiple depth planes in parallel, speeding up the reconstruction of the entire volume. Our experimental results confirm that GPU reconstruction is much faster than that of central processing unit (CPU).
