Lightness and brightness [PDF]
Current Biology, 2007 What is lightness? Lightness is the perceptual dimension that runs from black, through gray, to white. The physical counterpart of lightness is the permanent property of a surface that determines what percentage of light the surface reflects. Surfaces that appear white reflect about 90% of the light striking them. Black surfaces reflect about 3%.

Characteristics of Photon Beam and Preservation of Coherence in Fourth-Generation Light Sources
Applied Sciences, 2021 Fourth-generation storage rings (4GSRs) that exploit the multi-bend achromat lattice concept may be able to surpass the brightness and coherence that are attained using the present third-generation storage rings.

Brightness of Synchrotron radiation from Undulators and Bending Magnets [PDF]
, 2014 We consider the maximum of the Wigner distribution (WD) of synchrotron radiation (SR) fields as a possible definition of SR source brightness. Such figure of merit was originally introduced in the SR community by Kim.

Effect of Gamma Radiation on Greasy and Scoured Wool, Irradiated in Mini-Bale Form
Journal of Natural Fibers, 2022 The effect of gamma radiation dose on certain properties of wool treated in either greasy or scoured form in mini-bales was investigated. Specific properties studied include color (yellowness and brightness), solubility (alkali solubility and urea ...
