Abstract

We have demonstrated the high-speed confocal fluorescence lifetime imaging microscopy (FLIM) by analog mean-delay (AMD) method. The AMD method is a new signal processing technique for calculation of fluorescence lifetime and it is very suitable for the high-speed confocal FLIM with good accuracy and photon economy. We achieved the acquisition speed of 7.7 frames per second for confocal FLIM imaging. Here, the highest photon detection rate for one pixel was larger than 125 MHz and averaged photon detection rate was more than 62.5 MHz. Based on our system, we successfully obtained a sequence of confocal fluorescence lifetime images of RBL-2H3 cell labeled with Fluo-3/AM and excited by 4αPDD (TRPV channel agonist) within one second.
