intensity

A Dictionary of Astronomy | 1997 | Copyright

intensity (symbol I^v or I^λ) A measure of the radiant power passing through unit area into unit solid angle in unit interval of frequency or wavelength. Intensity is also equal to the flux density received from unit solid angle of an extended source (sometimes known as surface brightness). It is a characteristic of the source and does not depend on distance. For a given observing frequency, intensity is proportional to the brightness temperature. The units are W/m² per Hz per steradian, or Jy/sr. In infrared astronomy, the unit W/m² per μm per steradian is often used.

intensity

A Dictionary of Computing | 2004 | | Copyright

intensity A nontechnical synonym for both luminance and brightness. Luminance is the measured light intensity reflected or emitted by a surface in a given direction per unit of apparent area. Brightness is a psycho-physiological attribute of visual perception in which a source appears to emit or reflect more or less light.
