Abstract :
We have developed a fast hardware friendly bi-exponential fluorescence lifetime algorithm suitable for 2D CMOS single-photon avalanche diode (SPAD) arrays. The performance of the proposed algorithm against other techniques is demonstrated on the data from a plant specimen (Convallaria) by using 0.13μm CMOS SPAD arrays mounted on a multi-beam multi-photon microscopy system.
