Software adds fourth dimension to metrology
A
Digital Surf product story

Mountains Technology V5 users can correlate the evolution of a surface texture parameter with the evolution of another physical unit and to study the statistical dispersion of a roughness parameter.
Metrological analysis of the evolution of a 3D surface in a fourth dimension is now possible using the new 4D software module in Mountains Technology Version 5 from Digital Surf.
Changes in height on the Z axis are now not only a function of the X and Y position but also of a fourth dimension: T, which is most often time but can also be temperature, pressure, magnetic field or any other physical constraint applied to an object or surface for the purpose of studying its reaction.
4D surface visualisation is particularly spectacular.
Simulated flights over 3D surfaces changing in time can be output to a video file for animated presentations.
Analysis features include tools for manipulating and quantifying 4D series of surfaces.
It is possible to follow the evolution of a point or a zone over time, to correlate the evolution of a surface texture parameter with the evolution of another physical unit and to study the statistical dispersion of a roughness parameter.
The KLT (Karhunen-Loeve Transform) makes it possible to automatically identify zones on a surface that behave differently, with a view to locating them and studying them separately.
