1. A method for optically examining vessel walls of a blood vessel with a probe through intervening fluid, the method comprising:

  • inserting the probe into the blood vessel;

    generating optical signals with the probe and directing the optical signals to the vessel walls;

    receiving optical signals from the vessel walls through the intervening fluid at the probe;

    analyzing the received optical signals to perform a proximity analysis to determine whether the probe is close enough to the vessel walls to enable assessment of the vessel walls by comparison of the received optical signals to a reference relating to a known characteristic of said intervening fluid; and

    using the received optical signals to assess the vessel walls using spectral analysis of the optical signals when the probe is determined to be close enough to the vessels walls from the proximity analysis to enable the assessment of the vessel walls by the spectral analysis.
