The　reconstruction　quality　of　in-line　holography　suffers　from　the　superposition　of　twin　images,　which　blurs　the　details　and　degrades　the　quality　of　the　object　wavefront　reconstruction.　We　present　an　iterative　reconstruction　method　to　eliminate　twin　image　and　truthfully　retrieve　the　object　wavefront.　This　algorithm　has　a　better　elimination　effect　and　more　rapid　rate　of　convergence　than　other　phase　retrieval　methods.　An　experimental　setup　was　built　with　dual　cameras　recording　the　holograms　simultaneously,　thus　this　technique　can　be　employed　for　investigating　fast　dynamic　phenomina.　The　effectiveness　of　the　proposed　method　is　validated　using　different　samples.　©　(2013)　Trans　Tech　Publications,　Switzerland.
