Near IR time resolved spectroscopy has been studied for quantitative determination of
absorbance in highly scattering medium such as tissue. When a very narrow optical pulse is …

Near-infrared spectroscopy is a well-established technique that has been applied to a
variety of medical diagnostic problems. Recent examples include detecting peripheral …

When a picosecond light pulse is incident on biological tissue, the temporal characteristics
of the light backscattered from, or transmitted through, the sample carry information about …

Quantitative determination of chromophore concentrations by near infrared spectroscopy
(NIRS) is possible by using the differential pathlength of the detected light, measured …

We present a new data reduction algorithm to quantify absorption and reduced scattering
coefficients of living tissues. The method requires source-detector separations larger than 2 …

A diffusion model of noninvasive absorption spectroscopy was used to determine how the
change in signal resulting from a point absorber depends on the position of that absorber …

Optical imaging and tomography in tissues can facilitate the quantitative study of several
important chromophores and fluorophores. Several theoretical models have been validated …

The time spectrum of photons diffusely reflected from a turbid medium such as tissue
following a short incident light pulse depends on the optical absorption and scattering …

The noninvasive measurement of variations in absorption that are due to changes in
concentrations of biochemically relevant compounds in tissue is important in many clinical …

We report on time-resolved reflectance imaging experiments on a scattering medium
containing a spatially limited absorber. The medium is illuminated at two positions with …
