Master thesis – Physics-Based Simulation & Reinforcement Learning for Photochromic Light Control (w/m/d)
PROFACTOR is a research and technology company focusing on industrial inspection, robotic/digital assistance, micro/nano-manufacturing, and digital printing technologies. We research and develop the production of the future. Our technological developments optimize the production of renowned industrial partners.
Photochromic materials enable reversible color changes when exposed to light of specific wavelengths. In the REPIX project, a novel AI-assisted exposure system is developed to control spatially resolved photochromic state transitions on functional surfaces.
The project combines physics-based optical modeling with reinforcement learning to enable intelligent light control strategies for industrial applications.
Your Tasks
The goal of this thesis is to contribute to the development of a simulation-driven AI control framework for photochromic lightpatterning.
- Further development of a physics-based 2D simulation of photochromic thin films
- Integration of experimentally measured material parameters
- Development and implementation of a reinforcement learning framework for exposure control
- Design of state and action spaces for light modulation
- Definition of reward functions for color accuracy and pattern fidelity
- Evaluation of sim-to-real transfer strategies The exact focus (simulation vs. RL emphasis) can be adapted based on the candidate’s strengths.
