Determination of a Biological Absorber Depth Utilizing Multiple Source−Detector Separations and Multiple Frequency Values of Near-Infrared Time-Resolved Spectroscopy

Visualization of the photon path in scattering media is attempted through the use of frequency response analysis of near‐infrared time‐resolved spectroscopy (NIR‐TRS) spectra. The effect of the source−detector distances and the modulation frequency on the photon path is examined. It was found that t...

Zusammenfassung:	Visualization of the photon path in scattering media is attempted through the use of frequency response analysis of near‐infrared time‐resolved spectroscopy (NIR‐TRS) spectra. The effect of the source−detector distances and the modulation frequency on the photon path is examined. It was found that the use of multifrequency information could lead to the possibility of obtaining the information of an absorber's depth without increasing the number of measurements.
