Abstract

The invention provides a liquid detection device and method. The liquid detection device comprises: a pulse light source configured to emit pulse light; a time domain dispersion device configured to convert the pulse light emitted by the pulse light source from a frequency domain to a time domain to form pulse light after time domain broadening; a first spatial dispersion device configured to change the propagation direction of the light with different frequencies in the pulse light after time domain broadening in space; a first objective lens configured to converge the pulse light of which the propagation direction is changed by the first spatial dispersion device to a micro-flow device; the micro-flow device configured to enable a to-be-detected liquid in the micro-flow device to flow ata preset speed; a second objective lens configured to collect the light which is converged by the first objective lens and passes through the micro-flow device; a second spatial dispersion device forspatially recombining the light collected by the second objective lens; and a photoelectric detection device configured to image the light recombined by the second spatial dispersion device so as todetect the micro particles in the liquid.

Description

technical field [0001] Embodiments of the present disclosure relate to a liquid detection device and a liquid detection method. Background technique [0002] Liquid detection devices, such as blood analyzers for blood samples, water quality analyzers for river water quality, etc., are instruments for qualitative and quantitative analysis of formed components in liquids, such as particles, and provide relevant information. Automated liquid analyzers can be mainly divided into resistance type or comprehensive application type using multiple high-tech according to their working principles. The sampling data is processed by computer to obtain the number and rough classification of cells or other particles in the liquid. [0003] The liquid analysis speed of the above-mentioned liquid analysis device is relatively slow, but the price is high, and it is still difficult to popularize in routine detection. Contents of the invention [0004] The present disclosure provides a liqui...
