2. Surface metrology - Wikipedia

   en.wikipedia.org/wiki/Surface_metrology

   Focus variation: This method delivers color information, can measure on steep flanks and can measure on very rough surfaces. The disadvantage is that this method can not measure on surfaces with a very smooth surface roughness like a silicon wafer. The main application is metal (machined parts and tools), plastic or paper samples.

3. Surface roughness - Wikipedia

   en.wikipedia.org/wiki/Surface_roughness

   On rough soil surfaces, the action of rainsplash detachment tends to smoothen the edges of soil surface roughness, leading to an overall decrease in RR. However, a recent study which examined the response of smooth soil surfaces on rainfall showed that RR can considerably increase for low initial microroughness length scales in the order of 0 ...

4. Quality control system for paper, board and tissue machines

   en.wikipedia.org/wiki/Quality_control_system_for...

   Sensors measuring the paper quality (online meters) are attached to a sensor platform that move across the web guided by the scanner beam. A typical crossing time for a sensor platform is 10–30 s (an 8 m web, 60 cm/s). The sensor platform scans across the paper web and continuously measures paper characteristics from edge to edge.

5. International roughness index - Wikipedia

   en.wikipedia.org/wiki/International_roughness_index

   A common misconception is that the 80 km/h used in the simulation must also be used when physically measuring roughness with an instrumented vehicle. IQL-1 systems measure the elevation profile, independent of speed, and IQL-3 systems typically have correlation equations for different speeds to relate the actual measurements to IRI.

6. Profilometer - Wikipedia

   en.wikipedia.org/wiki/Profilometer

   A diamond stylus is moved vertically in contact with a sample and then moved laterally across the sample for a specified distance and specified contact force. A profilometer can measure small surface variations in vertical stylus displacement as a function of position.

8. Pacing (surveying) - Wikipedia

   en.wikipedia.org/wiki/Pacing_(surveying)

   Pacing is a reasonably easy and quick method of measuring distance in the field. [1] It is used to measure a distance and is often used with a sighting or a hand compass. Most commonly, pacing is split up into segments, such as chains, which are set measures of distance. By determining one's own pace, distance can easily be estimated.

9. Surveyor's wheel - Wikipedia

   en.wikipedia.org/wiki/Surveyor's_wheel

   Thus counting revolutions with a mechanical device attached to the wheel measures the distance directly. Surveyor's wheels will provide a measure of good accuracy on a smooth surface, such as pavement. On rough terrain, wheel slippage and bouncing can reduce the accuracy. Soft sandy or muddy soil can also affect the rolling of the wheel.
