Pocket reflectometry

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.

Variable distance absolute reflectometry

Journal of the Optical Society of America A, 2012
In many interferometric applications the variation of the reflected light intensity due to the separation distance change between two optical systems is the raw signal from which some unknown parameters must be determined. We consider the general situation in which the signal offset and amplification, the initial separation, and the optical properties ...

Imaging reflectometry in situ

Applied Optics, 2007
An innovative method of in situ real-time optical monitoring of thin film deposition and etching is presented. In this technique, intensity maps of a thin film corresponding to a series of wavelengths selected by a monochromator (300-800 nm) are recorded by a CCD camera.

Subpicosecond-time-domain reflectometry

Optics Letters, 1981
We demonstrate a new method of optical time-domain reflectometry using subpicosecond pulses and nonlinear detection. The high-spatial-resolution ( approximately 15-microm) temporal resolution and sensitivity put new limits on the size and nature of defects that can be detected, localized, and analyzed in optical fibers.

Submillimeter optical reflectometry

Journal of Lightwave Technology, 1989
The development of optical reflectometers with a spatial resolution in the submillimeter range is reviewed. Optical time-domain reflectometers (OTDRs) and optical low-coherence reflectometers (OLCRs) for nondestructive diagnostics of waveguide devices are discussed.

Neutron reflectometry

2009
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.

Refractometry by reflectometry

SPIE Proceedings, 1995
Complex 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.
