Method and device for simultaneous multi-channel and multi-method acquisition of synchronized parameters in cross-system fluorescence lifetime applications

摘要

A device for simultaneous multi-channel, multi-method acquisition of synchronized parameters in fluorescence lifetime applications is provided with a fluorescence macroscope, microscope or nanoscope, a pulsed laser source, a beam splitter, a TSCSPC detector, and a synchronized peripheral device. A sample is irradiated with a pulsed, high frequency, polarized or unpolarized ps or ns laser beam. The fluorescence radiation from the sample is guided onto a beam splitter to generate two partial beams that are deflected onto a list-mode detector operating by space- and time-correlated single photon counting. All physical parameters of each photon are acquiring by the list-mode detector simultaneously and saved in control electronics. Simultaneously, further parameters are acquired in synchronization by a peripheral device and saved. The saved parameters of the list-mode detector and of the peripheral device are combined to a multi-parameter, multi-method acquisition system in a 1-file method.
