SM3LDV

AUR Inc.

The SM3LDV draws upon successful research in developing sub-miniature LDV systems to produce a very high resolution three-velocity component probe. Uncertainties are maintained at very low levels in this multi-axis optical design. Probe dimensions smaller than compact digital cameras are achieved in this innovative design.

The SM3LDV is ideally suited for situations with limited optical and hardware access.

Complex 3D flow diagnostics;
- Automotive tests such as in-cab defroster measurements
- In-flight tests
- Velocity measurements for turbine blade cooling models
- High-speed testing
- In-model probe mounting for probe/model vibration coupling
- Turbulence research

Our SM3LDV is a complete solution including turn-key support photonics hardware and data acquisition and processing hardware. AUR- developed software including data acquisition, processing, and post-processing software allows you to quickly obtain results for your application. AUR also has sub-miniature traverse systems for one-, two-, or three-axes of motion for your SM3LDV.
