Significance: Beer–Lambert law (BLL) is a widely used tool for contact and remote
determination of absorber concentration in various media, including living tissues. Originally …

This review describes the diffusion model for light transport in tissues and the medical
applications of diffuse light. Diffuse optics is particularly useful for measurement of tissue …

The application of functional near-infrared spectroscopy (fNIRS) in the neurosciences has
been expanding over the last 40 years. Today, it is addressing a wide range of applications …

Continuous-wave near-infrared spectroscopy and near-infrared imaging enable the
measurement of relative concentration changes in oxy-and deoxyhemoglobin and thus …

A thorough understanding of optical properties of biological tissues is critical to effective
treatment planning for therapies such as photodynamic therapy (PDT). In the last two …

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 …

This article reviews the basic principles of frequency-domain near-infrared spectroscopy (FD-
NIRS), which relies on intensity-modulated light sources and phase-sensitive optical …

Near-infrared spectroscopy (NIRS) can be used to noninvasively measure changes in the
concentrations of oxy-and deoxyhemoglobin in tissue. We have previously shown that while …

This review celebrates the 30th anniversary of the first in vivo near-infrared (NIR)
spectroscopy (NIRS) publication, which was authored by Professor Frans Jöbsis. At first …

Photobiomodulation, also known as low-level laser/light therapy (LLLT), refers to the use of
red-to-near-infrared light to stimulate cellular functions for physiological or clinical benefits …
