Simple instrument for the chracterization of diffuse reflectance [PDF]

, 1999
An apparatus for the measurement ofthe radial dependence ofthe continuous-wave diffuse reflectance ofa tissue is described. It consists in a probe, which is applied on the tissue, and a detection unit.

Hyperspectral Classification of Cyperus esculentus Clones and Morphologically Similar Weeds

Sensors, 2020
Cyperus esculentus (yellow nutsedge) is one of the world’s worst weeds as it can cause great damage to crops and crop production. To eradicate C. esculentus, early detection is key—a challenging task as it is often confused with other Cyperaceae and ...

Pepper Plants Leaf Spectral Reflectance Changes as a Result of Root Rot Damage

Remote Sensing, 2021
Symptoms of root stress are hard to detect using non-invasive tools. This study reveals proof of concept for vegetation indices’ ability, usually used to sense canopy status, to detect root stress, and performance status.

Two Methods of Near Infrared Reflectance Spectroscopy for Determining the Digestibility and Energy Value of Feeds [PDF]

, 1997
Two groups of rations with known in vivo digestibility and energy values were used in this study. These rations were composed of Italian ryegrass only (lRO. n = 45), and combination of Italian ryegrass and concentrates (lRC, n = 58).

Remote sensing reflectance reconstruction to obtain water optical properties from MERIS multispectral satellite images [PDF]

, 2010
We use a multiple regression analysis and a data bank of about 400 reflectance spectra to reconstruct hyperspectral reflectances between 400 and 900 nm with a 5 nm step using only the values known at the wavelengths of the MERIS sensor level 2 data.

Reflecting on Čerenkov reflections [PDF]

Journal of Physics: Conference Series, 2008
Magic Telescope may observe and reveal at horizons lights from air-shower Cherenkov reflections. The ground, the sea, the cloudy sky (below the mountain) may reflect PeVs-EeV UHECR Cherenkov lights observable by MAGIC telescopes. Even rarest UHE neutrino skimming the atmosphere or skimming the Earth may induce upward-horizontal airshowers: a new ...

Calibration of BRDF Based on the Field Goniometer System Using a UAV Multispectral Camera

Sensors, 2022
The bidirectional reflectance distribution function (BRDF) is important for estimating the physical properties of a surface in remote sensing. In the laboratory, the BRDF can be estimated quickly and accurately using a goniometer, but it is very ...
