“…Scanning probe microscopes (SPMs), microcoordinate measuring machines (microCMMs), and optical measurement systems are major dimensional measurement technologies for nanomanufacturing [87]. In this section, recent accomplishments in measurement technologies are presented as an update of the related past CIRP keynotes [38,94,215].…”

“…The measurement area of the optical scanner may vary from 175 x 140 to 2000 x 1600 [mm 2 ] and its declared resolution is 20 µm in all directions (x, y, z). The accuracy of identifying the points depends on the measurement area, the distance between single probing points, the method of measurement responsible for registration of the cloud of points corresponding to the measured object, and on the data processing method [25]. The dimensions of concrete surfaces sometimes exceed 10000 mm and then they can be considered as large scale details.…”

The paper presents examinations of the surface of base concrete with a 3D scanner. Two base concrete surfaces, differently prepared, were examined, together with two measurement strategies: simple and fast 3D scanning and partial scanning in selected areas corresponding to the device measurement space. In order to complete the analysis of a concrete surface topography an original Matlab-based program TAS (Topography Analysis and Simulation) was developed for both 2D and 3D surface analyses. It enables data processing, calculation of parameters, data visualization and digital filtration.

“…That is why we propose that optical inspection methods, technology enable the use of non-invasive, i.e., not through contact with the surface is completely clean and samples depending on its constitution can be reused [3], [4], [6], [8], [14], and [15]. Since 2009, I have been conducting research in the field of optical metrology and image processing, developing a model for the evaluation of surface roughness in the paper industry, based on texture analysis using co-occurrence matrix of gray levels [23], [24], [25], [26] industrial sectors.…”

A means of facilitating the transfer of Optical inspection methods knowledge and skills from academic institutions and their research partners into Panama optics and optical research groups is described. The process involves the creation of an Integrated Knowledge Group Research (IKGR), a partnership led by Polytechnic University of Panama with the support of the SENACYT and Optics and Optometry Department, Polytechnic University of Catalonia. This paper describes the development of the Project for knowledge transfer "Implementation of a method of optical inspection of low cost for improving the surface quality of rolled material of metallic and nonmetallic industrial use", this project will develop a method for measuring the surface quality using texture analysis speckle pattern formed on the surface to be characterized. The project is designed to address the shortage of key skills in the field of precision engineering for optical applications. The main issues encountered during the development of the knowledge transfer teaching and learning are discussed, and the outcomes from the first four months of knowledge transfer activities are described. In overall summary, the results demonstrate how the Integrated Knowledge Group Research and new approach to knowledge transfer has been effective in addressing the engineering skills gap in precision optics for manufactured industrial sector.
