The multispectral reflectance of shortwave radiation by agricultural crops in relation with their morphological and optical properties [PDF]

, 1978
Relations between morphological properties of uniform canopies. optical properties of the leaves and reflection of shortwave radiation, in the visible light region and the near infrared, by crops are the subject of this thesis.The aim of the study was a ...

A Portable Spectropolarimeter for Field Crop Canopies: Distinguishing species and cultivars of fully developed canopies by polarized light

Plant Production Science, 2002
A spectropolarimeter equipped with eight spectral bands in the visible, near– and short–wave infrared ranges (490–2200 nm) as well as a rotary film polarizer has been developed for measuring the reflectance and degree of polarization of light reflected ...

Simplified Set-Up for Near-Specular Solar Reflectance Measurement

SolarPACES Conference Proceedings
In Concentrating Solar Power (CSP) plants, mirrors are used to redirect solar radiation onto a receiver. More precisely, the solar radiation, diverging with a half-angle of about 4.7 mrad, impinges off-normal on the mirror.
