Proceedings of the 2008 workshop on Immersive projection technologies/Emerging display technologiges, 2008
We developed a bidirectional reflectance distribution function (BRDF) display that reproduces the texture of objects and rays of a light field. Our BRDF display is based on the technology used in integral photography (IP), which was originally investigated for use in 3D displays.

ACM SIGGRAPH 2007 posters, 2007
We propose a BRDF display that reproduces the textures of a light field. Conventional displays are now high-definition (HD). HDdisplays are ideal in terms of their excellent resolution. This, of course begs, the questions of whether resolution is the most important factor when judging the quality of a display?

OSA Annual Meeting, 1993
By combining scatterometry with polarimetry, a polarization dependent BRDF is measured with the potential to separate roughness, contamination, and subsurface damage. Two instruments which measure the polarization BRDF will be presented and results discussed.

To derive BRDF archetypes from POLDER-3 BRDF database
2014 IEEE Geoscience and Remote Sensing Symposium, 2014In this study, based on kernel-driven linear BRDF model, a new spectral vegetation index named anisotropic flat index (AFX) and a hotspot kernel function are described. Anisotropic Flat Index (AFX), which is created by normalization of net scattering magnitude with the isotropic scattering, can summarize the variability of basic dome-bowl anisotropic ...

SPIE Proceedings, 1990
A Bidirectional reflectance distribution function (BRDF) error analysis is given. Errors in measuring each of the components of BRDF are analyzed and a total RMS error calculation is given. A computerized error analysis allows each of the terms to be tested for their effect on the total error.

View planning for BRDF acquisition
ACM SIGGRAPH 2003 Sketches & Applications, 2003The estimation of the bi-directional reflectance distribution function (BRDF) of a 3D object requires reflectance measurements under numerous viewing and lighting directions. This sketch summarizes our method to select advantageous directions.

SPIE Proceedings, 1989
In-plane scatter at 0.6328 μ m was measured from a master set of four samples at 18 optical scatter measurement facilities in the United States. They included government laboratories, universities and industry. The samples were a diffuse white, diffuse black, Molybdenum mirror (45 A rms) and Aluminum mirror (7 A rms).

Remote Sensing Reviews, 2000
Laboratory studies of the bidirectional reflectance distribution function (BRDF) have greatly improved our understanding of the bidirectional reflectance characteristics of natural and man‐made surfaces. Explorative research and model validation studies in astronomy, remote sensing, material science, and computer graphics have likewise increased the ...

Probabilistic water BRDF model
ILSC 2023: Proceedings of the International Laser Safety Conference, 2023Is a reflecting surface, and therefore can be a hazard source when illuminated by a laser beam. The extent of the hazard has been a matter of concern on a regular basis over the years, with disallowing interactions of laser beams with water being the most conservative approach.

Techniques for BRDF evaluation
The Visual Computer, 2021Bidirectional reflectance distribution functions (BRDFs) describe how light interacts with a point on a surface. To propose a new BRDF formulation or to compare different reflectance representations, it is necessary to confront the results obtained with those functions against previous work or measured data.
