A synchroscan streak camera was adapted to a microscopic system for fluorescence lifetime measurements. By using this device together with a synchronously pumped dye laser system, a time resolution of 40 ps was attained. Recent applications of this technique include the fluorometric detection of chlorophyll from microscopic parts of spruce needles to measure defects within the photosynthetic system after exposition to environmental pollutants or their photooxidants and fungal infection. It was found that after a combination of continuously high ozone concentration and infection by Rhizosphaera Kalkhoffii, the relative fluorescence intensity of a chlorophyll component with a decay time of 550 ps decreased significantly, whereas a component d...
