Henderson %J Sensors %D 2012 %I MDPI AG %R 10.3390/s120505650 %X We have successfully demonstrated video-rate CMOS single-photon avalanche diode (SPAD)-based cameras for fluorescence lifetime imaging microscopy (FLIM) by applying innovative FLIM algorithms. We also review and compare several time-domain techniques and solid-state FLIM systems, and adapt the proposed algorithms for massive CMOS SPAD-based arrays and hardware implementations. The theoretical error equations are derived and their performances are demonstrated on the data obtained from 0.13 ¦Ìm CMOS SPAD arrays and the multiple-decay data obtained from scanning PMT systems. In vivo two photon fluorescence lifetime imaging data of FITC-albumin labeled vasculature of a P22 rat carcinosarcoma (BD9 rat window chamber) are used to test how different algorithms perform on bi-decay data. The proposed techniques are capable of producing lifetime images with enough contrast. %K fluorescence lifetime imaging microscopy %K FLIM %K CMOS %K single-photon avalanche diode %K single-decay %K multi-decay %K time-domain FLIM %K lifetime based sensing %U http://www.mdpi.com/1424-8220/12/5/5650
