Abstract
The conventional method of applying the arctangent operation at every picture element in an interferogram slows down the phaseshift 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 phaseshifted intensities. Performance tests on different types of processors reveal a two to seven times increase in computational speed using the method.
