  • Patent number: 11015981
    Abstract: The invention relates to a method for the two-dimensional reconstruction of wave fronts (104) of light for use in an optical system (100) comprising: measuring the distribution function of the light intensity in at least two images at different optical planes (101, 102) having an optical path difference. In particular this method is suitable for probing the tomographical distribution of wave fronts of electromagnetic fields with an image detector, e.g. any standard two-dimensional camera.

  • Patent number: 10230940
    Abstract: A method for determining the complex amplitude of the electromagnetic field associated with a scene, comprising a) capturing a plurality of images of the scene by means of a photographic camera, the images being focused in planes of focus arranged at different distances, wherein the camera comprises a lens of focal length F and a sensor arranged at a certain distance from the lens in its image space, taking at least one image pair from the plurality of images and determining the accumulated wavefront to the conjugate plane in the object space corresponding to the intermediate plane with respect to the planes of focus of the two images of the pair.
