Friedrich Fleischmann

Prof. Dr. Ing. Friedrich Fleischmann serves as a Professor at the Faculty of Production Engineering, University of Bremen, with his office located at Neustadtswall 30, 28199 Bremen (Building E, Room 208). His institutional affiliation spans multiple research initiatives focused on optical metrology and precision engineering within Germany's academic framework.

His research program centers on advanced metrology techniques for freeform optical surfaces, with particular emphasis on experimental ray tracing methodologies, gradient sensor development, and characterization of both reflective and transmissive optics. Key research thrusts include the measurement of mid-spatial-frequency errors in progressive lenses, LED beam shaping optics, and high-precision verification of complex optical components. His work bridges theoretical optical design with industrial manufacturing applications, addressing critical challenges in optical quality control.

Analysis of his 15 most recent publications (2019-2025) reveals a cohesive research trajectory focused on experimental ray tracing as a unifying methodology. His work demonstrates consistent innovation in surface reconstruction algorithms (particularly radial basis functions), sensor integration for gradient measurement, and cross-validation of optical metrology techniques across diverse applications from ophthalmic lenses to industrial lighting systems. The publications show strong methodological continuity between simulation frameworks and physical measurement validation.
