description A detection device for tiny particles in a liquid is provided. The detection device includes a flow cell, a laser, a scattered light collection device, a photoelectric detector, a fiber Bragg grating and a first optical fiber coupler, wherein scattered light collected by the scattered light collection device is sent to the fiber Bragg grating through the first optical fiber coupler, and reflected light of the fiber Bragg grating after receiving the scattered light is sent to the photoelectric detector through the first optical fiber coupler. The device can eliminate most scattered light generated by the liquid, and reduce the interference of the scattered light of the liquid to scattered light signals generated by the particles, so that the scattered light signals captured by the photoelectric detector are mainly light signals generated by the particles.
