ABSTRACT:
An imaging flow cytometer is provided with a continuous-emission light source for continuously monitoring cells passing through the image capturing area of a video camera for cell-image capturing, and with an excitation light source for picking up a fluorescent image of a cell. When a line sensor monitoring cell passage through the cytometer senses such cell passage, the cell is irradiated with strobe light and then, after waiting for the cell to move a fixed distance, with the excitation light. Thus, a particle analyzer is provided in which an image by white light resulting from the strobe light and a fluorescent image resulting from the excitation light can be captured simultaneously by a single video camera in either upper and lower halves or right and left halves of one imaged frame.
