Martijn Anthonissen: Optimal mass transport for inverse design in nonimaging optical systems

This is a recording of Martijn Anthonissen's invited talk at the Nonimaging Optics Minisymposium, which was organized on Dec 8, 2025. The full title was Models using optimal mass transport for inverse design in nonimaging optical systems Martijn Anthonissen works at Eindhoven University of Technology in the Computational Illumination Optics group. This is one of the few mathematics groups worldwide working on optical design problems from illumination optics. The team has a healthy portfolio of PhD positions and close collaborations with industrial partners. The research focuses on nonimaging freeform optics, imaging optics and improved direct methods. 00:00:00 – Welcome & introduction of speaker 00:01:16 – Inverse design problem & frog-to-prince example 00:02:22 – TU/e Computational Illumination Optics group & research lines 00:05:18 – Nonimaging free-form optics & application examples (street lighting, headlights) 00:06:27 – Unified framework for 16 basic reflector/lens systems 00:07:48 – 1D/2D modeling: optical mapping, energy conservation & optimal transport 00:13:24 – Extension to 3D: Monge–Ampère, generalized Monge–Ampère & generated Jacobian equations 00:18:53 – Numerical solution strategy & least-squares solver 00:19:48 – Design examples: laser beam shaping, point-to-parallel reflectors, SIAM logo, egg-to-chick target 00:23:05 – Summary and future work (AI for optics, finite sources, GRIN, phase information) 00:24:30 – Q&A: energy vs étendue, real source characteristics, wave-optics integration, manufacturing constraints 00:30:33 – Q&A: 1D crossover, cylindrical/saddle freeform surfaces
