Abstract
The present invention is directed to a device and method for determining the presence of fluorescent molecules, locations thereof, and number of fluorescent molecules in a local area irradiated with excitation light based on the number of fluorescence photons generated per unit period of time by the irradiation of the excitation light counted as a quantized fluorescence intensity of the fluorescence molecules and a distribution of appearance frequencies of the fluorescence photons formed on a two-dimensional image. In accordance with the present invention, a device is provided which comprises a light source for irradiating excitation light to a local area on a flat substrate with the adsorbed fluorescent molecules, and fluorescence detecting means for detecting fluorescence photons from the fluorescent molecules and for forming a distribution of appearance frequencies of the fluorescence photons per unit period of time on a two-dimensional image corresponding to the local area.
