SYSTEM AND METHOD FOR ANALYZING A LIGHT BEAM CONDUCTED BY A BEAM-CONDUCTING OPTICAL UNIT

A system and a method for analyzing a light beam guided by a beam guiding optical unit. The system has a graduated neutral density filter arrangement (120, 520), which is arranged in a far field plane of the beam guiding optical unit and has at least one graduated neutral density filter (121, 521, 5...

Summary:A system and a method for analyzing a light beam guided by a beam guiding optical unit. The system has a graduated neutral density filter arrangement (120, 520), which is arranged in a far field plane of the beam guiding optical unit and has at least one graduated neutral density filter (121, 521, 522, 523) having a spatially varying transmission, and a light intensity sensor arrangement having at least one light intensity sensor (140, 540), which is arranged in a near field plane of the beam guiding optical unit and is configured to measure (141, 541, 542, 543), for each graduated neutral density filter (121, 521, 522, 523) of the graduated neutral density filter arrangement (120, 520), a light intensity transmitted by each graduated neutral density filter.
