Different materials reflect light in different ways, so reflectance is a useful surface descriptor. Existing systems for measuring reflectance are cumbersome, however, and although the process can be streamlined using cameras, projectors and clever catadioptrics, it generally requires complex infrastructure.

Refractometry by reflectometry
SPIE Proceedings, 1995Complex refractive index determination (refractometry) of metals can be made successfully with methods using reflectivity measurements. In this paper a brief classification of reflectivity methods with subsequent comments about their sensitivity is made. Experimental results obtained using the most suitable methods are presented.

Reflectometry of the precorneal film
Acta Ophthalmologica, 1985Abstract. In order to gain information about the thickness of the oily layer of the precorneal film, a clinical method of measuring the reflectivity of the precorneal film was developed. The method entails the use of a slit‐lamp photometer to measure the reflectivity at 2 selectecd wavelengths, 500 and 700 nm, at 20° incidence.

ACM SIGGRAPH 2011 papers, 2011
We present a simple, fast solution for reflectance acquisition using tools that fit into a pocket. Our method captures video of a flat target surface from a fixed video camera lit by a hand-held, moving, linear light source. After processing, we obtain an SVBRDF.

Review of Scientific Instruments, 1997
Reflectometry will be used on ITER to measure the density profile in the main plasma and divertor regions, and to measure the plasma position and shape in order to provide a standby reference for the magnetic diagnostics in long pulse discharges. The high temperatures of the ITER core and the resultant significant relativistic downshift of the second ...

Abstract Neutron reflectometry, in which neutrons are reflected from planar structures, is a powerful method for investigating properties of interfaces. It is one of the neutron techniques in most demand today and neutron reflectometers are amongst the first instruments to be commissioned at the new pulsed sources SNS and J-PARC.

Bevölkerungswachstum und Klimawandel haben tiefgreifende Veränderungen im Mekong Delta verursacht. Eine dieser Veränderungen betrifft das zunehmende Auftreten extremer Hochwasserereignisse. Um das Leben der Menschen in den Küstenbereichen des Deltas während solcher Ereignisse zu schützen, ist es von großer Bedeutung, die Wasserstandhöhe in diesen ...
