ABSTRACT:
An oximeter probe segment with a first fiber optic for carrying light to a patient, and a second fiber optic for carrying return light from the patient. The light is of a wavelength spectrum which can be shifted by travelling through the first and second fiber optics. The probe segment includes an element which is configured to provide a signal corresponding to the shift of the wavelength spectrum through the first and second fiber optics. This signal can either be used to actually measure the shift, or the signal can itself be a coded value corresponding to the shift.
