| attenuation coefficient |
(Also called extinction coefficient, especially in reference to optical frequencies.) For radiation propagating through a medium, the fractional depletion of radiance per unit pathlength, or in radar usage, of the power density of plane-wave radiation per unit pathlength. The attenuation coefficient is defined through Bouguer's law as where L is the monochromatic radiance at a given wavelength, is the attenuation coefficient, and ds is a differential increment of pathlength. ...

| attenuation |
Blocking or modulation of the excitation light intensity can be accomplished with a series of filters that transmit increasing percentages of the incident light or with an acousto-optic tunable filter (see AOTF).

| attenuation |
In physics, any process in which the flux density (or power, amplitude, intensity, illuminance, etc.) of a "parallel beam" of energy decreases with increasing distance from the source. Attenuation is always due to the action of the transmitting medium itself, mainly by absorption and scattering. In meteorological optics, the attenuation of light is termed extinction.
