The standard 3D miniLDV System consists of three miniLDV probes in a custom-designed alignment bracket, three Processing Engine hardware processors with USB interface, and the 3D Burst Processor Acquisition Manager software, which synchronizes the three systems and calculates 3D measurement statistics.

The 3D miniLDV is a modular design consisting of three fully independent systems, so it is perfect for research facilities with a variety of experimental projects. (Contact us regarding custom systems comprised of a single miniLDV system and a 2D miniLDV system.)

With the continuing tradition of ease of use and short time from setup to results, the 3D miniLDV System becomes an attractive alternative to 3D PIV techniques such as Stereo PIV.
