In particular a double-exposure specklegram is considered. The ensemble-average intensity in the Fourier plane is analytically derived and fringe visibility is investigated. The theoretical results are verified by in-plane displacement translation experiments.enghttps://v2.sherpa.ac.uk/id/publication/issn/0950-0340info:eu-repo/semantics/articleBirefringenceFourier opticsImage recordingPhotographySpeckleVisualizationDouble exposure specklegramFringe visibility analysisScale aperturesSpeckle photographyImage analysis2021-04-12Angel, LTebaldi, MTrivi, MBolognini, N10.1080/09500340110062261
