Surface quality of plastic material acrylonitride-butadiene-styrene (ABS) in a polycarbonate (PC) blend was investigated by probing samples obtained from industry using a HeNe laser beam. Peculiar optical behaviour such as a dynamic speckle pattern f

A diffractive optical element (DOE) based sensor is presented for measurement of gloss differences of injection molded convex or concave plastic products. Increases of local gloss of the samples, and hence local wear of the tool, were observed to cor

In this paper, we present three new types of diffractive-optical-element (DOE)-based glossmeters (DOGs) that have been developed for both laboratory and online local specular gloss measurements of objects in industrial processes. The three are denote

Optical properties of different type of surface treatments of titanium biomaterial as polishing, grinding, and chemical etching are investigated in details. The main aim of this study is in sensing the organisation of nano-scale fibrinogen and oligon
The aesthetic appearance of various objects is important to human beings. One measure of the quality of an object is its surface quality, which can be characterized with the concept of gloss. Nowadays measurement of the gloss is a routine off-line me
