(57) [Abstract] [PROBLEMS] A still image of particles intermittently flowing in a fluid is displayed. The purpose is to capture and analyze efficiently. A flow cell that surrounds particles with a sheath liquid to flow, a trigger light source that constantly irradiates particles with trigger light, a laser pulse light source that emits pulsed light when capturing particles, and a trigger light source. A particle detector that detects that the light has crossed the particle of the particle and generates a detection signal, a means for emitting a laser pulse light source based on the signal from the particle detector, and a condenser lens that irradiates the particle with pulsed light. An objective lens and an image pickup unit for picking up a still image of particles by pulsed light, and an image processing unit for processing and analyzing the obtained still image. |
