Abstract
A fluorescence lifetime measurement apparatus includes a first controller controlling a total gate length and a second controller controlling a start gate length of a plurality of gate lengths into which the total gate length is divided. The start gate length is a time window whose start time is when measurement of the number of fluorescence photons of a specimen starts. The apparatus also includes a measurer measuring the number of fluorescence photons for each of the gate lengths; a processor calculating a fluorescence lifetime the specimen based on the start gate length and the number of fluorescence photons; and a third controller causing, when the fluorescence lifetime does not satisfy a predetermined condition, the first and second controllers to change the start gate length and the total gate length.
