Digital micromirror device-based adaptive optics approach for enhanced micro-machining fidelity

Outline - Past work and challenges in DMD projection-based laser manufacturing - DMD mask shifting - Taking advantage of limited bandwidth - Custom substrates, including cell growth assays - Conclusions Will go through some of our past work, along with challenges we’ve faced. Will show how a combination of mask repositioning on the DMD and exploiting limited bandwidth can overcome some of these problems. Will show some of the work we’re doing towards cell growth assays. Developing laser manufacturing techniques, with UK industrial partners, for high-precision, high-speed, flexible etc fabrication - applications in sensing, bio-medicine, metamaterials, etc etc etc. DMDs offer many advantages for laser machining, which have yet to be established in industry. Not just beam shaping, but other more advanced techniques, which the group at Southampton are pioneering, and I will talk about some of these today.
