Lasers for Particle Image Velocimetry


Particle Image Velocimetry (PIV) achieved significant development compared with traditional flowing display technology by using a transient, multi-point, non-contact hydrodynamic speed method. PIV overcome the single point measurement limitations of traditional means for that PIV can record a good deal of velocity distribution of different space at the same transient state, also provide customers affluent spatial structure and flowing characteristics about the flow field. PIV can be widely used in the wind tunnel flow field measurements, turbulent flow field measurements, particle flow studies, environmental studies, biomedical research and other fields.

Changchun New Industry referred to CNI ( is mainly engaged in the research and production of high-end lasers. CNI has obtained ISO9001, FDA, CE, RoHS and JQA certification. CNI products have been exported to more than one hundred countries and regions and CNI also received a high market reputation in the international community. CNI can provide different structured laser/ line laser for PIV, also the accessories used for PIV are available for a total system from customers.
