Proceedings of SPIE - The International Society for Optical Engineering 7718 : -. ScholarBank@NUS Repository. https://doi.org/10.1117/12.853632||Abstract:||Speckle photography explores the possibility of determining the motion like in-plane translation and out-of-plane rotation or tilt of optically rough surface from the speckle shift that takes place at the recording plane. A simple correlation based speckle photographic system has been proposed that implements two simultaneous optical extended fractional Fourier transforms (EFRTs) of different orders using only a single lens and detector to simultaneously detect both the magnitude and direction of translation and tilt by capturing only two frames: one before and another after the object motion. Theoretical analysis and experiment results are presented. © 2010 Copyright SPIE - The International Society for Optical Engineering.||Source Title:||Proceedings of SPIE - The International Society for Optical Engineering||URI:||http://scholarbank.nus.edu.sg/handle/10635/73642||ISBN:||9780819481917||ISSN:||0277786X||DOI:||10.1117/12.853632|
