title = "Adaptive phase-shifting digital holography compensating positional inaccuracy and tilting of optics",
abstract = "The phase-shifting errors mainly result from the imprecise movement of phase-shifter and the vibration of system. These geometric errors are classified into the positional inaccuracy and tilting of optics. And they can be represented as the longitudinal and transversal displacements of interferograms on the hologram plane. In this paper, we propose adaptive phase-shifting digital holography compensating these two displacements and this proposed method is based on genetic algorithm for finding optimized variables corresponding to real system. By computer simulations, the deteriorations in reconstruction image are modeled and the chromosomes are constituted. We find the fittest solution compensating the longitudinal and transversal displacements experimentally and present the reconstruction images by encoding the resultant holograms on a spatial light modulator.",
