Abstract
Methods and apparatus relating to the imaging of biological samples are provided. More particularly, they relate to the detection of light emanating from fluorescent species present in a sample in order to study the structure and dynamics of such a sample. Such a method of analysis comprises irradiating the sample with a pulse of excitation energy causing fluorescent species in the sample to fluoresce; detecting light emanating from the sample during a predetermined period of time after the pulse; generating and storing data recording at least the wavelength of the detected light against time; and analysing the data with reference to the respective lifetimes of the fluorescent species to detect the presence of the respective emissions from three or more different fluorescent species which emit light simultaneously during at least part of said predetermined period, which are indistinguishable from each other on the basis of their wavelength or lifetime alone.
