The feasibility of retroreflective PIV recording has been investigated with several configurations. The setups varied in the form of the source and cutoff grid, the arrangement of illumination, and the size, type and velocity of the flow field examined. In general, relatively low laser power and overall low-cost equipment was needed in comparison to standard PIV, and the Field of View was easily scalable when compared to in-line PIV.
