摘要：
A spectrophotometric instrument, including:
a source of measurement light signals having measurement light wavelengths;
a source of a probe position recognition light signal at a recognition wavelength which is different than the measurement light wavelengths ;
a probe for coupling the measurement light signals and the probe position recognition light signal into tissue, and for receiving the measurement light signals and the probe position recognition light signals from the tissue;
a detector coupled to the probe for generating electrical signals representative of the light received at the probe; and
a processor/controller coupled to the detector for determining the position of the probe with respect to an object as a function of the detected recognition light signal.
