The present disclosure relates to techniques for imaging tissue of a subject. An exemplary method comprises transitioning the liquid crystal light shutter to the closed state to prevent the global shutter imager from receiving visible light; illuminating the tissue of the subject with the fluorescence excitation illumination source to accumulate charge at a plurality of pixels of the global shutter imager, while the liquid crystal light shutter is in the closed state; reading a set of accumulated charge at the plurality of pixels of the global shutter imager to produce a set of imaging data; and generating a fluorescence image frame based on the set of imaging data.
