    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 ...

    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...
