Abstract: The present invention relates to a system and method for reconstruction of temporal wavefront changes for use in an optical system comprising: measuring the distribution function of the light intensity, e.g. the two-dimensional distribution function of the light intensity, in at least two different images taken at different times, wherein said images are taken in at least one optical plane, e.g. the same optical plane, of the optical system.

Abstract: The disclosure relates to a method for characterizing and operating a display, such as a light-field display or a display with or without a phase screen, comprising: an input stage wherein at least one test signal is provided as input to the display, a capture stage for obtaining display output information, said capture stage comprising capturing, by at least one acquisition system placed at a distance from the display, an impulse response of the display in response to the at least one provided test signal, wherein said capturing of an impulse response comprises measuring the at the at least one acquisition system received intensity distribution of the light emitted by the display in response to the at least one test signal, and/or capturing the wavefront phase of the light emitted by the display in response to the at least one test signal.
