Abstract
Fluorescence lifetime microscopy has been widely used in quantifying
cellular interaction or histopathological identification of different
stained tissues. A novel, to the best of our knowledge, approach for
high-throughput multiplexed fluorescence lifetime imaging is
presented. To establish a high-throughput fluorescence lifetime
acquisition system, a uniformed illumination optical focus array was
generated by a novel computer-generated hologram algorithm based on
matrix triple product. This, in conjunction with an array detector and
multichannel time-correlated single-photon counting, enables the full
use of the acquisition ability of each detector. By utilizing interval
segmentation of photon time detection, a high-throughput multiplexed
fluorescence lifetime imaging is achieved. Experimental results
demonstrate that this method achieves a fivefold increase in the
collection throughput of fluorescence lifetime and is capable of
simultaneous dual-target fluorescence lifetime measurement.
