Velocity fields can be measured nearly instantaneously, with high accuracy and high spatial and temporal resolution by means of a LDV-system. Laser measurements are performed routinely in the SVA since 1985. For this application SVA provides compact probes with integrated solid-state laser (PowerSight probe from TSI). The probes are portable and flexible in use. In the cavitation tunnel, a 2D LDV is mainly used. In the towing tank and for mobile tasks primarily a 1D system is applied. Both compact probes can be combined into a 3D measuring system. When a submersible probe is required, a waterproof 2D probe (83 mm diameter) can be coupled to the laser module via optical fibers.<\/p>\n
