A new method for the detection of low oxygen concentration is proposed here. The system is based on the principle of enhancement of fluorescence yield of tetraphenylporphine (TPP) dye at λ=656 nm when excited by He-Cd laser at λ =441 nm in the pres

The possibility of optical oximetry of the blood in the fetal brain measured across the maternal abdomen just prior to birth is under investigation. Such measurements could detect fetal distress prior to birth and aid in the clinical decision regardi

Near infrared (NIR) measurements were made from the ma- ternal abdomen (clinical studies) and laboratory tissue phantoms (ex- perimental studies) to gain insight into photon migration through the fetal head in utero. Specifically, a continuous wave s

We present tissue phantom experimental results and theoretical simulations to study photon migration through the fetal head in-utero. A continuous-wave (CW), dual wavelength (760 & 850 nm) spectrometer was developed and employed for the experiments a
