1. An apparatus for monitoring fetal cerebral oxygenation during childbirth comprising:

  • a source of infrared photons;

    a probe to optically access a single location on the scalp of a fetus by injecting the infrared photons generated by said photon source at said location, and for receiving scattered photons reflected from within the skull of the fetus at said location; and

    at least first and second detectors for detecting the presence of photons received by said probe at at least two different delay intervals so as to provide for distinguishing photons reflected at different instants or from different depths within the head of the fetus on the basis of said different delay intervals.
