Abstract
An axially swept light sheet fluorescence microscope has illumination optics capable scanning the focus region of a line beam along an illumination optical axis to illuminate a light sheet in a sample plane, and detection optics capable of collecting fluorescence light from the sample plane and imaging the collected light on a light detector with a rolling shutter. A microcontroller synchronizes the rolling shutter with the scanning of the focus region. The illumination optics performs the axial scanning using a linear phased array of independently controllable electrostatically driven optical elements controlled by the microcontroller.
