Beer-Lambert law along non-linear mean light pathways for the rational analysis of Photoplethysmography
Photoplethysmography (PPG) is a technique that uses light to noninvasively obtain a volumetric measurement of an organ with each cardiac cycle. A PPG-based system emits monochromatic light through the skin and measures the fraction of the light power which is transmitted through a vascular tissue and detected by a photodetector. Part of thereby transmitted light power is modulated by the vascul...
متن کاملModified Beer-Lambert law for blood flow.
We develop and validate a Modified Beer-Lambert law for blood flow based on diffuse correlation spectroscopy (DCS) measurements. The new formulation enables blood flow monitoring from temporal intensity autocorrelation function data taken at single or multiple delay-times. Consequentially, the speed of the optical blood flow measurement can be substantially increased. The scheme facilitates blo...
متن کاملComment on the modified Beer-Lambert law for scattering media.
We present a concise overview of the modified Beer-Lambert law, which has been extensively used in the literature of near-infrared spectroscopy (NIRS) of scattering media. In particular, we discuss one form of the modified Beer-Lambert law that is commonly found in the literature and that is not strictly correct. However, this incorrect form of the modified Beer-Lambert law still leads to the c...

15 صفحه اولSlow-light enhancement of Beer-Lambert-Bouguer absorption
Optical techniques are finding widespread use in chemical and bio-chemical analysis, and Beer–Lambert– Bouguer (BLB) absorption in particular has become one of the classical workhorses in analytical chemistry [1]. During the past decade, there has been an increasing emphasize on miniaturization of chemical analysis systems [2] and naturally this has stimulated a large effort in integrating micr...
