Popis:	One dimensional imaging of fluorescence lifetimes was performed directly for the first time in a premixed, atmospheric-pressure ethylene/air flame. A picosecond laser system based on the microscope-DFDL (Distributed-Feedback Dye Laser) was used for excitation of OH. The method involves imaging a section of the flame onto the streak camera and evaluating a series of windows, each with a certain number of channels of the CCD-multichannel plate. In this way, changes in quenching efficiency can be monitored along a horizontal line through the flame. These direct lifetime measurements confirm the observations of relative lifetimes previously obtained for this flame by saturated 2D-LIF.
