  • Light-field imaging based on tilt-aberration
    Patent number: 12689836
    Abstract: A method, imaging system and computer program product for obtaining a transverse phase gradient of a wave field from at least a first and a second wavefield intensity map includes the steps of; capturing at a first incoherent tilt aberration the first wave field intensity map of a target at a first degree of incoherent tilt aberration, using a filter positioned between a source of electromagnetic radiation and an electromagnetic radiation detector capturing said first wave field intensity map; capturing at a second and different incoherent tilt aberration said second wave field intensity map of said target at a second degree of incoherent tilt aberration, using a filter positioned between a source of electromagnetic radiation and an electromagnetic radiation detector capturing the second wave field intensity map; determining the transverse phase gradient on the basis of at least a difference of logarithms of wavefield intensity maps divided by the magnitude of the difference between the first incoherent tilt
