3D PIV system is based on the original 2D PIV system but uses the principle of stereoscopic imaging to add the third dimension. At least two sets of cameras view the test area from different angles and with the two sets of two-dimensional velocity vector components a third velocity vector component can be calculated within the test area. The image is first calibrated, and afterward this third velocity component can be evaluated. Microvec has been developing proprietary PIV technology and has been constantly improving and implementing new techniques and algorithms based on the latest research in the field since 2002. It has a history of constantly introducing new and innovative techniques and algorithms such as Pressure PIV in 2014 or Light Field PIV in 2017.
