Abstract
A beam propagation camera has at least one beam-splitting optical arrangement (240) configured to split a beam, which is incident on the beam-splitting optical arrangement along an optical axis (OA) of the beam propagation camera, into a multiplicity of sub-beams, and a sensor arrangement (250) configured to detect the sub-beams. The beam-splitting optical arrangement has a diffractive structure (241) configured such that at least two of the sub-beams are spatially separated from one another on the sensor arrangement and have respective foci longitudinally offset from one another along the optical axis.
