What is BSDF? Light illuminating a surface may be reflected, transmitted or absorbed. The patterns of that interaction encode information about surface shape, material composition and structure. The quantitative representation of these patterns is the Bidirectional Scattering Distribution Function (BSDF). BSDF radiometrically characterizes the scatter of optical radiation from and through a surface interface as a […]

As we push the envelope to devise creative solutions to global problems, researchers have concentrated their efforts on the emerging field of metasurfaces. A metasurface is an engineered two-dimensional material designed to manipulate electromagnetic waves, such as light, in ways that are not possible with natural materials. These surfaces consist of arrays of subwavelength structures, […]

Building designers and developers that are pursuing the Heat island reduction credit for LEED certification require documentation of the Solar Reflectance Index (SRI) for their project’s roofing materials, shade giving structures, and paving materials. Under the U.S. Green Building Council’s LEED 2009 rating system, credits SSc7.1 and SSc7.2 (combined as credit SSc5 in LEED v4) […]

Crop monitoring for nutrients, water-stress, disease, insect attack and overall plant health is a vital aspect of successful agricultural operations. Traditionally this has been carried out by visual examination of crops on the ground or sometimes from the air. However these methods are limited by the ability of the human eye to discriminate between healthy […]

Hyperspectral imaging is a powerful tool in applied spectroscopy. Hyperspectral cameras measure light from a scene in hundreds of contiguous spectral bands. A two-dimensional image is created, where each pixel contains a full spectrum. Here we discuss the most important specifications for hyperspectral imaging cameras, and how they relate to various applications. Spectral Range The […]

In the context of reflectance measurements, the specular and diffuse components refer to different ways in which light interacts with a surface and is reflected or scattered. Specular Reflection Specular reflection refers to the mirror-like reflection of light from a surface. When light hits a smooth and polished surface, such as a glass mirror or […]
