|Title:||High-speed phase-shift computation using dynamic memory processing||Authors:||Ng, T.W.||Keywords:||Dynamic memory processing
|Issue Date:||1996||Citation:||Ng, T.W. (1996). High-speed phase-shift computation using dynamic memory processing. Optical Engineering 35 (12) : 3482-3484. ScholarBank@NUS Repository.||Abstract:||The conventional method of applying the arctangent operation at every picture element in an interferogram slows down the phase-shift technique. A method that precalculates and dynamically stores the phase combinations in the computer's random-access memory is introduced. The appropriate value is then mapped out based on input phase-shifted intensities. Performance tests on different types of processors reveal a two to seven times increase in computational speed using the method. © 1996 Society of Photo-Optical Instrumentation Engineers.||Source Title:||Optical Engineering||URI:||http://scholarbank.nus.edu.sg/handle/10635/58348||ISSN:||00913286|
