We discuss the application of time domain fluorescence techniques to the recovery of targets embedded in several cm thick biological tissue. Considering the general time domain problem first, a singular value analysis is used to study the optimal use of multiple frequency components extracted from time domain data. Furthermore, a computationally efficient algorithm is presented to tomographically reconstruct fluorophore locations using their decay amplitudes and validated using phantom experiments. The reconstruction algorithm presented here has wide applicability for non-invasive, diagnostic fluorescence imaging in small animals and other biological systems, given that fluorescence lifetime is a sensitive indicator of local tissue environment and elementary interactions at the molecular level.
