Combining deformable mirrors and DPPs for multi-conjugate AO

Our colleagues from the Dynamic Optics and Photonics Group at the University of Oxford, UK presented their first results using our transmissive Deformable Phase Plate (DPP) to implement multi-conjugate adaptive optics (MCAO) at the Photonics West 2020 conference.

MCAO is an effective solution to overcome the limited Field-of-View due to field-dependent aberrations (size of the isoplanatic patch) by using multiple wavefront modulators. However, because of the significant complications of implementing multiple deformable mirrors in already complex microscopes, MCAO have so far remained at the simulation level for microcopy applications. The team at the University of Oxford used the combination of a deformable mirror and our transmissive deformable phase plate to to simplify these prohibitive complexities.


The versatility and ease of integration of a DPP can bring MCAO one step closer to real microscopy applications and enable large field of view aberration correction.
