Abstract
An apparatus is described for measuring hemodynamic or metabolic function of an organ or tissue region of a subject comprising a super-continuum laser operating in the near or short-wave infrared wavelength range and comprising a multi-stage amplifier. A source fiber delivers the super-continuum emission to the organ or tissue region, and a collection fiber receives reflected emission from the region. A detector followed by a processor is used to determine a metabolic state and an oxygenation state of the organ or tissue region. A signal-to-noise ratio of the signal is improved using a dual-arm differential measurement technique.
