We describe a TCSPC FLIM system that uses 8 parallel TCSPC channels to record FLIM data at a peak count rate on the order of 50⋅106 s-1. By using a polychromator for spectral dispersion and a multi-channel PMT for detection we obtain multi-spectral FLIM data at acquisition times on the order of one second. We demonstrate the system for recording transient lifetime effects in the chloroplasts in live plants.
