Abstract
A flow imaging system based on matrix laser scanning are provided. In the system, a beam splitter component modulates continuous laser generated by a laser source, and the continuous laser is focused on a focal plane by an illumination objective to form matrix spots. The matrix spots are irradiated on a single-cell axial flow of a fluid focusing component. When cells in the single-cell axial flow pass through the matrix spots, a fluorescent signal and a scattered light signal generated are received by a light collecting objective, and then sent to a photoelectric detector through a condenser. The photoelectric detector converts the fluorescence and scattered light signals excited into voltage signals, and the collecting card collects and converts the signals into digital signals, and sends the digital signals to a computer to be recovered through the computer, so as to obtain a cell image.
