Unlocking the Secrets of Hidden Worlds: iNIRS Reveals Turbid Media Dynamics
Industry: The paper introduces interferometric near-infrared spectroscopy (iNIRS) as a novel
method for quantifying optical and dynamical properties of turbid media, offering significant
advancements over conventional techniques.
Challenge: Existing methods like continuous-wave (CW) near-infrared spectroscopy (NIRS)
require complex assumptions and additional dimensions for accurate quantification of optical
properties. Diffuse correlation spectroscopy (DCS) techniques, while useful, lack time-of-flight
(TOF) resolved measurements crucial for dynamic property determination.
How GaGe Digitizers were used: Measurements of the absorption and scattering of infrared light can provide information, for example, about blood oxygenation and tissue composition. A Gage digitizer was used to monitor signals from two photodetectors –one that measures raw laser power and a second connected to the signal from the infrared interferometer that contains the sample. The Gage waveform data are then used to produce final infrared absorption and scattering measurements.
Extraordinary Aspects of the Paper: iNIRS simplifies measurement complexities by
preserving the photon distribution of time-of-flight, offering shot-noise limited sensitivity, and
concurrently determining optical properties and dynamics using a single optical path. This
approach surpasses limitations of existing techniques and holds promise for real-time, in vivo
tissue analysis.
This paper’s innovative approach to spectroscopy could revolutionize how we understand and
analyze biological tissues, offering simplified yet comprehensive insights into their optical and
dynamic properties
