Abstract
A plurality of light emission molecules, having different light emission lifetimes, are irradiated with excitation light so that the light emission molecules emit light. The emitted light is divided into at least two different wavelength regions. Temporal changes in each of the at least two wavelength regions of the light emission is measured over at least two different time periods. Information on energy transfer generated between the plurality of light emission molecules is determined based on the measured results in each of the wavelength regions over each of the time periods.
