<p>A pulse exciting light emitted from a laser light source (10) is allowed to scan in a first direction by a first scanning means (100), and then scan in a second direction perpendicular to the first direction by a second scanning means (120) before being condensed by an objective optical system (140) in order to irradiate a sample (50). Fluorescence emitted from the sample (50) is passed through the objective optical system (140) to the second scanning means (120) and runs in the second direction perpendicular to the first direction to be output to an optical isolating means (110) thence passed to a streak camera (30) where it is recorded as a time variation of fluorescence intensity. Fluorescence lifetime is calculated based on the time variation of fluorescence intensity and a fluorescence lifetime distribution image is formed.</p> |
