Should you be looking for technical information about instrument techniques and in particular optical surface texture instruments, Optical measurement of surface topography published by Springer is a book not to be missed.
This collective work edited by Professor Richard Leach contains several chapters written by leading specialists of each technique.
Chapters cover the following techniques:
Chromatic confocal microscopy
Point autofocus instruments
Focus variation instruments
Phase-shifting interferometry
Coherence scanning interferometry
Digital holographic microscopy
Imaging confocal microscopy
Light scattering methods.
Most of these techniques are supported in the ISO 25178-60x series but this book provides more detailed information and describes a variety of case studies.
Another excellent reference book is Characterisation of areal surface texture, also published by Springer. This book describes post-processing and filtering methods in detail as well as surface texture parameters and also provides several practical applications.
A major complement of the areal ISO standards if you want to understand practical areal surface metrology.
Chapters cover the following techniques:
Areal field parameters
Areal feature parameters
Areal filtering methods
Areal form removal
Areal fractal methods
Choosing appropriate parameters
Characterization of individual features
Multi-scale signature of a surface
It also describes a range of applications including solar cells, cylinder liners, laser structured cams and road surfaces.
Application examples can also be found in scientific publications where authors explore material properties or process efficiency using surface texture tools.

This paper explores several surface texture parameters and analyses to characterize abrasive grains, using several instrument techniques.
Impact of GEM foil hole geometry on GEM detector gain (2015)
This paper exposes a characterization method of the geometry of gas electron multiplier holes using contour and step height analyses.
Influence of grinding conditions on the topographic characteristics of machined surfaces (2014)
Using frequency analysis, wavelets, fractal and motifs analysis, this paper demonstrates the differentiation of turning and grinding surfaces of same Sa value, depending on machining conditions.
Use of close range photogrammetry to assess the micro-texture of asphalt surfacing aggregates (2013)
Results obtained from 3D volume parameters for tracking wear on rock aggregates.
The MountainsMap® Reference Guide is the documentation installed with the software that can be displayed by pressing the F1 key anytime.
But it is not only a user help guide on how to use the software, it also contains valuable metrological information on standards, filters, as well as on mathematical algorithms used such as the Fourier transform or the autocorrelation function.
This online reference guide is available on paper as a reference manual, a 750-page book printed in color, in English, German and French.
