Method for recording temporal changes in the time function of an optical signal with spatial resolution along a line in space

摘要

Method for recording temporal changes in the fluorescence decay function along a line within a spatially extended sample, characterized in that the sample is repeatedly scanned with the beam of a high-frequency pulsed light source along said line, individual photons of the fluorescence, phosphorescence or stimulated by the light source diffuse scatter signals are detected, for each photon the distance along the line, the time within the laser pulse period and the time after any event inside or outside the sample is determined and the distribution of the number of photons is built up over these parameters.
