Luminance while imaging luminance meters measure luminance in a way similar to the way a digital camera records color images. 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
Random measure a random measure formula_38, the measure formula_39 satisfying for every positive measurable function formula_41 is called the intensity measure of formula_5. The intensity measure exists for every random measure and is a s-finite measure. For a random measure formula_38, the measure formula_44 satisfying for all positive measurable functions is called the supporting measure of formula_38. The supporting measure exists for all random measures and can be chosen to be finite. For a random measure formula_38, the Laplace transform is defined as for every positive measurable function formula_41. For a random measure formula_5, the integrals and formula_52 for positive formula_2-measurable formula_41
