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%.

Error Analysis of Atmospheric Visibility Measurements Based on an Image Brightness Contrast Method
IEEE Access, 2020 The method of image visibility detection is one of the methods closest to human vision. It is based on the principle of human eye observation but avoids the errors resulting from human subjectivity.

Perception of Brightness and Brightness Illusions in the Macaque Monkey [PDF]
The Journal of Neuroscience, 2002 Recent physiological studies show that neural responses correlated with the perception of brightness are found in cortical area V1 but not earlier in the visual pathway (Kayama et al., 1979; Reid and Shapley, 1989; Squatrito et al., 1990; Komatsu et al., 1996; Rossi et al., 1996; MacEvoy et al., 1998; Rossi and Paradiso, 1999; Hung et al., 2001 ...

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.
