PARTICLE DETECTION DEVICE, FLOW CYTOMETER, AND PARTICLE DETECTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a fluid detection device that hardly generates variance in measurement result by calculating a suitable irradiation position and automatically performing light irradiation positioning.;SOLUTION: A particle detection device includes a first light source 11 which irradiates a detection object 111 moving in a flow passage 113 with light, first detection means 10 including a first detection part 13 which detects first optical information generated by irradiating the detection object with the light from the first light source, a second light source 21 arranged downstream from the first detection means and emitting light, a light deflector 22 deflecting the light from the second light source to irradiate the detection object moving in the flow passage with the deflected light, second detection means 20 including a second detection part 23 which detects second optical information that the detection object irradiated with the deflected light from the optical deflector detects, and control means 30 for controlling the optical deflector based upon position information on the detection object obtained from the first optical information so as to irradiate the detection object with the deflected light.;COPYRIGHT: (C)2013,JPO&INPIT
