Abstract
A fluorescence life measuring apparatus, a fluorescence life measuring method and a program are described that can obtain fluorescence life using a simple configuration. The apparatus moves a stage on which a fluorescent material to be measured is placed, irradiates with excitation light the fluorescent material placed on the stage moved at a constant speed, images afterglow of emitted fluorescence caused by the excitation light, and uses an imaged image to detect the elapsed time from a fluorescence position and afterglow strength at a target afterglow position and calculate the fluorescence life.
