| 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. ...

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).
