lu·mi·nance

(lū'mi-nănts),
The brightness of an object, expressed as the luminous flux per unit solid angle per unit projected area, measured in lamberts or in candelas per square meter.
[L. lumino, to light up, fr. lumen, light]

luminance

the brightness of a light-emitting source (e.g., a view box or computer monitor).

luminance

Photometric term characterizing the way in which a surface emits or reflects light in a given direction. It is equal to the luminous intensity measured in a given direction divided by the area of this surface projected on a perpendicular to the direction considered. Symbol: L. Units: candela per square metre (SI unit); footlambert; lambert, etc. See brightness; candela per square metre; footlambert; lambert; lightness; millilambert; nit; photometry; SI unit.

They found that luminance affects decision-making in different ways, with higher and lower levels of light intensity.
In the next step in the process, weighting factors for the characteristics of the roadway are used to determine a road class, which then determines the luminance level.
Spatial frequency: High-frequency (detailed) data are best represented by monochromatic color maps that only differ in luminance (Mullen 1985).
While participants observed the luminance disks, we recorded brain magnetic fields in a magnetically shielded room using a 160-channel wholehead MEG system (PQ1160C; Yokogawa, Tokyo, Japan).

The light transmission and luminance attenuation in fog for coloured and white LEDs was investigated at different fog densities.
In this study, we suggest a concave MLA (or "planar concave" MLA, hereinafter called "concave" MLA) as an optical pattern in the LGP, which shows a higher luminance than the convex MLA (or "planar convex" MLA, hereinafter "convex" MLA) for the same point light sources.
