摘要：
A simple closed-form relation for extracting the absorption coefficient of a multiply scattering medium from a measured temporal impulse response is pointed out. Such a relation eliminates the need for time-consuming iterative curve-fitting techniques and may also be of use for calculating the regional sensitivity of the time-resolved spectroscopy technique. Equations for three types of measurement geometry (reflection from an infinite half-space, transmission through an infinite slab, and reflection from an infinite slab) are described. The effects of detector temporal resolution and detector intensity linearity are also discussed. (C) 1997 Optical Society of America.
