High-speed channel demixing by scanning interferometric focusing with binary transmission matrix

In this paper, we demonstrate a fast binary intensity modulation based on the measurement of the binary TM. For each correction, the binary TM was calculated based on measurements of the intensity change at the target with a series of input masks. After preloading the measurement masks, the DMD can run at full speed during measurement. The system allows dynamic focusing at 12.5 Hz with 1024 input modes, and more than 60 times intensity enhancement. We demonstrate focusing light through a highly dynamic scattering sample, a live drosophila embryo.
