Paper Abstract

Off-axis holography records a three-dimensional object into a two dimensional hologram through Leith-Upatneiks geometry. The recovery of 3D object from off-axial hologram, termed as an inverse problem, has been previously implemented by back-propagating (BP) reconstruction. Here we demonstrate the possibility of reconstruction of 3D object from off-axis hologram by combining back-propagating with two-step iterative shrinkage/thresholding algorithms (Twist) and compare it with back-propagating reconstruction of off-axis holography. The results of simulations and experiments show that Twist-BP reconstruction has better performance in eliminating out of focus noise.
