Modelling the sampling volume for skin blood oxygenation measurements
The absolute quantified measurement of haemoglobin skin blood saturation from collected reflectance spectra of the skin is complicated by the fact that the blood content of tissues can vary both in the spatial...

Measurement of Cerebral Venous Saturation in Adults using Near Infrared Spectroscopy
Saturation measurements have long been used to provide information about oxygenation levels within tissue in the form of a single percentage value. Whilst the measurement of peripheral arterial oxygen saturati...

The Noninvasive Measurement of Absolute Cerebral Deoxyhemoglobin Concentration and Mean Optical Path Length in the Neonatal Brain by Second Derivative Near Infrared Spectroscopy
We have used second differential near infrared spectroscopy of water to determine the mean optical path length of the neonatal brain. By obtaining the ratio of the second differential features of deoxyhemoglob...

Speckle interferometric observations of supernova 1987A and of a bright associated source
The explosion of SN1987A in the Large Magellanic Cloud1 provides a unique opportunity for the direct measurement, by means of interferometry, of the spatial distribution and evolution of the optical emission of ...
