Laser Rugosimeter

The shape of a surface can be measured with great details by our laser rugosimeter.


Laser rugosimeter

By sweeping the surface with an inline laser, our rugosimeter measures the heights with a resolution of 0.5 mm in the 3 dimensions (standard configuration). The width of the band measures 50 cm and the length can measures several meters (2 m in standard configuration) (either 4 million points of measurement). We obtain a digital topographic map with high-resolution of the object measured in about ten minutes.

Images of micro-topography

If we use it primarily to measure the roughness of the grounds (crusting, soil erosion), the instrument is suitable to any other surface. For large surfaces, it is possible to digitally link several measured bands. The instrument can be used in laboratory like in the fields.
