Title:
FLOW CYTOMETER, METHOD FOR CALCULATING POSITION, AND PROGRAM
Document Type and Number:
Japanese Patent JP2022014302
Kind Code:
A
Abstract:
To detect a position of passage in a depth direction in a flow passage as an observation target.SOLUTION: A flow cytometer includes: a micro fluid device; a light source; an optical detector for detecting, in time-series, intensity of a signal light emitted from an observation target object flowing in a flow passage, the signal light being formed by irradiating the observation target object with illumination light; an information generator for generating optical information showing a structure of the observation target object on the basis of the intensity of the signal light; an operator; and a flow passage position controller. The operator includes: a signal intensity acquisition unit for acquiring electronic data showing change with time of the intensity of the signal light detected on the basis of a predetermined detection position in a flow passage for detecting the position in a depth direction of the flow passage when the observation target object passes through the flow passage; a scan unit for performing scan processing for moving the flow passage into a depth direction and acquiring electronic data in different depth positions; a position calculation unit for calculating a depth-direction position on the basis of electronic data; and an output unit for outputting positional information showing the position in the depth direction calculated by the position calculation unit.SELECTED DRAWING: Figure 4
