AbstractIn this paper, we present a method to simultaneously perform wavefront correction and random-access scanning based on a digital micromirror device (DMD) and binary holography. Previously, we reported an ultrafast DMD-scanner that operates at the DMD pattern rate, i.e., 22.7 kHz, for two-photon excitation (TPE) imaging and two-photon polymerization (TPP) applications. To enhance the imaging and fabrication resolution, e.g., imaging through turbid tissues, point spread function of the laser focus is engineered and optimized via superposing the scanning and wavefront correction holograms. Mathematical models have been derived; imaging and fabrication experiments are performed to verify the predicted performance.
