PhD abstract

The aim of this thesis is to provide the French Metrology with a reference instrument that can be used for measuring the appearance of objects. Several physical properties of object appearance are used not only to identify the object itself but also determine its quality. These include color, gloss, texture and translucency. This work describes the design, characterization and the implementation of an instrument that has been built particularly to measure the bidirectional reflectance distribution function (BRDF) of planar surfaces. BRDF is a physical quantity that enables measuring the surface color and gloss. Accordingly it is important to ensure accurate and traceable measurements of such a quantity in order for a comprehensive understanding of surface properties to be fulfilled. Some surfaces show pigmented, metallic, sparkling or pearlescent appearance. These surfaces, called goniochromatic surfaces, have the ability to change their appearance depending on the viewing angle. To characterize them, it is necessary to deliver surface reflectance measurements at several directions and under different illumination conditions. The instrument that enables these measurements is called gonioreflectometer. The experimental setup we have designed consists of two separate detection lines. The first line, called "spectral line", is used to study the color. It consists of a stationary illumination source that uses a xenon lamp spectrally resolved by a monochromator. The light coming out from the source is focused on the surface under investigation. The reflected light by the surface is collected by using a lens and directed onto a photodiode by a mirror. This detection system can be moved over a wide angular range so as to measure the BRDF. The second line, called "spatial line", is used to measure the gloss of the surface. In order to be very close to the average human observer, high angular resolution is required. In this line the detection part is stationary. It consists of a Charged Coupled Device (CCD) camera of 512 x 512 pixels. The source used to illuminate the surface is an incandescent tungsten lamp. Angular measurements in this line are provided by the movement of the illumination source itself. Both color and gloss lines share a robot sample-holder that provides six degrees of freedom. This of course facilitates measurements over varies detection and illumination directions of the sample.

PhD abstract

2.5D printing is between traditional color printing, for the process and its visual quality, and 3D printing, which makes forms and reliefs by ink superposition. Because of its properties, 2.5D printing could allow the realistic reproduction of objects and surfaces, but inks are too glossy. To reduce and control this glossy aspect of inks, we modulate the roughness of the printed layers, at the micro-scale, both in frequency and amplitude. Influence of parameters was measured, and different strategies were suggested to reduce sparkle and to allow the creation of matte colored layers: by constituting a 5D space where gloss and color are modeled, we can make gloss level of colored surfaces uniform.Several case studies form the Conservation of Cultural Heritage were considered, where 2.5D printing could help the curator, the conservator or the archivist. We studied in particular the issues of the the gap filling on an archaeological object, the realistic reproduction of surfaces, and the creation of matte objects for readability..

PhD abstract

Gloss is a visual appearance attribute. It is a construction from the visual system built on the optical signal from a surface and sensed by the eye. Recent developments in fundamental spectrophotometry lead to instruments able to measure luminous reflection with an acuity equal to the visual system in terms of angular resolution and dynamic. A cross-discipline description between optics and vision is now possible on a same set of samples. In this work, we build through sol-gel process a metrological gloss scale. It is multivariate in terms of surface topology, refractive indices, hue and gloss levels. This scale is then characterized in roughness, specular gloss and BRDF. We expose the measurement techniques and corrections used on our goniospectrophotomer ConDOR. This instrument is dedicated to high resolution measurement of specular peaks. By the end of this study, Condor has reached an angular resolution of 0.014°, the smaller achieved until now, twice better than the human visual system acuity. The dynamic range extends over 6.5 decades. ConDOR is used to measure BRDF of several glossy samples from different scales. These measurements are studied and discussed. A first link between roughness and BRDF is drawn.Using a reference gloss scale, we finally study two aspects of gloss perception: both effects of a change in the solid angle of illumination and in the observation environment realism. Our results indicate that the visual system is more sensitive to gloss variations under realistic conditions as well in lighting as in environment. This effect is particularly noticeable on matt samples. Lesser realistic or lesser natural conditions could lead observers to confusion.
