Time resolved imaging microscopy. Phosphorescence and delayed fluorescence imaging
Biophysical Journal, 1991 An optical microscope capable of measuring time resolved luminescence (phosphorescence and delayed fluorescence) images has been developed. The technique employs two phase-locked mechanical choppers and a slow-scan scientific CCD camera attached to a normal fluorescence microscope.
