Abstract
I will present a new fluorescence imaging method called LEAD (line excitation array detection) microscopy, capable of providing 0.8 million frames per second. This method performs line-scanning of excitation laser beam using a chirped signal-driven longitudinal acousto-optic deflector to create a virtual light-sheet, and images the field-of-view with a linear photomultiplier tube array to generate a 66×14 pixel frame each scan cycle. I will present an implementation of the LEAD microscopy as a blur-free 3D imaging flow cytometer with 3.5-micron resolution and signal-to-background ratios >200. I will also present its conceptual implementation as an ultrafast two-photon LEAD microscopy (2p-LEAD).
