Abstract Coating thickness is considered to be one of the most important characteristics thermally sprayed coatings. Therefore, it has long been goal able control it. This could achieved by implementing an online, closed-loop control. A prerequisite for such a mechanism feedback signal coating with sufficiently small measurement uncertainty. Optical distance techniques have demonstrated in past...

Abstract Bananas were examined starting from ripening stage R2 (green) to R7 (overripe), identify suitable non-invasive, real time in-situ technologies separate the stages: (1) Chlorophyll degradation, measured by DA meter, decreased ca. 2.1 (R2) 0.2 IAD units (R7), i.e. tenfold decline. (2) Colour CIE-Lab a values dramatically increased as indication of chlorophyll breakdown and enable differe...
