Abstract
Phasor plot analysis is one of the most powerful analysis technique in fluorescence lifetime imaging microscopy, especially for analysis of heterogeneous mixtures. Compared to frequency domain fluorescence lifetime measurement, time domain measurement offers information in various frequencies at once measurement, but needs high frequency sampling for stable signal acquisition, which requires a lot of memory in hardware and a long time for analysis, furthermore in TCSPC, acquisition time is extremely long due to low photon count rate. We suggest a new system with low pass filter, which leads to about 100 times faster measurement speed while maintaining precision and accuracy in usual modulation frequency.
