Summary

• What is new: Introduction of a rigorous wave-based optical amplitude optimization scheme for TVAM allowing high-resolution 3D printing over the full volume.
• Why this is important: Existing pattern optimization for TVAM is limited by resolution variations due to ray optical assumptions.
• What the research proposes: A wave optical optimization approach using an efficient angular spectrum method of plane waves with memory efficient gradients for realistic TVAM volumes.
• Results: Demonstrated potential for micrometer feature resolution across the full volume, surpassing the limitations of ray-optics based approaches.
