Beam control in multiphoton microscopy using a MEMS spatial light modulator

摘要

We demonstrate feasibility of a an spatially-modulated multi-photon microscopy (S-MPM) technique that can image through complex media that strongly scatters light, and we describe performance achieved with a prototype instrument. S-MPM's imaging advantages are enabled by a high-speed, microelectromechanical spatial light modulator (MEMS SLM) subsystem with 1020 independently controllable mirror segments.
