Processes of surface texture characterisation can be roughly divided into measurement
issues and analysis of the results obtained. Both actions can be fraught with various errors …

The metrology of so-called “engineering surfaces” is burdened with a substantial risk of both
measurement and data analysis errors. One of the most encouraging issues is the definition …

We discuss interesting effects that occur when strongly focusing light with m th-order
cylindrical–circular polarization. This type of hybrid polarization combines properties of the …

Various methods, based on both surface frequency and direction, can be alternatively
proposed to reduce the influence of high-frequency measurement and data analysis errors …

Errors that occur when surface topography is measured and analysed can be classified
depending on the type of surface studied. Many types of surface topographies are …

Coatings, taking comprehensive studies into account, cannot be considered without their
functional performance. When, generally, studying surfaces, a wide analysis of coatings …

The surface topography characteristics of the working surface of the gas valve cover of a gas
meter can be used to quantitatively evaluate the sealing performance of the gas valve. A set …
