BEAM PROPAGATION CAMERA AND METHOD FOR LIGHT BEAM ANALYSIS

摘要

The invention relates to a beam propagation camera and a method for light beam analysis. A beam propagation camera according to the invention comprises at least one beam-splitting optical arrangement (240) which splits a beam impinging on the beam-splitting optical arrangement along an optical axis (OA) of the beam propagation camera during operation into a plurality of partial beams, and a sensor arrangement (250) for detecting said partial beams, wherein the beam-splitting optical arrangement (240) has a diffractive structure (241), and wherein said diffractive structure (241) is designed in such a way that at least two of the partial beams on the sensor arrangement (250) are spatially separated from one another and have a focus offset in a longitudinal direction relative to the optical axis (OA).
