Abstract
We report onwide-field time-correlated single photon counting (TCSPC)-based fluorescence
lifetime imagingmicroscopy (FLIM) with lightsheet illumination.A pulsed
diode laser is used for excitation, and a crossed delay line anode image intensifier,
effectively a single-photon sensitive camera, is used to record the position and arrival
time of the photons with picosecond time resolution, combining low illumination
intensity of microwattswith wide-field data collection.We pair this detector with the
lightsheet illumination technique, and apply it to 3D FLIM imaging of dye gradients
in human cancer cell spheroids, and C. elegans.
