Luminance Luminance Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light that passes through, is emitted or reflected from a particular area, and falls within a given solid angle. The SI unit for luminance is candela per square metre (cd/m). A non-SI term for the same unit is the nit. The CGS unit of luminance is the stilb, which is equal to one candela per square centimetre or 10 kcd/m. Luminance is often used to characterize emission or reflection from flat, diffuse surfaces.

The Measure of a Man (Star Trek: The Next Generation) machine or not, Maddox's plans for reproducing him would lead to a situation tantamount to slavery. Picard uses this to defuse Riker's arguments, and turns the discussion to metaphysical matters of Data's sentience.

Data is intelligent and self-aware, and Picard asks anyone in the court to show a means of measuring consciousness. With no one able to answer this, Louvois acknowledges that neither she nor anyone else can measure this in Data and rules that he has the right to choose. Upon
