Limitations of laser profilometry in measuring surface topography of polycrystalline rocks (original) (raw)

This technical note discusses the limitations of laser profilometry in measuring the surface topography of polycrystalline rocks, particularly granite. It highlights the evolution from mechanical rugosimeters to laser profilometers, detailing the workings of the Kreon Zephyr KZ& 25 device. While laser profilometers offer advantages such as speed and non-contact measurement, the note addresses specific challenges associated with their use, including limitations in accuracy, resolution, and the operational constraints posed by device components.
