1. A method comprising:
performing an ablation by applying energy from a catheter to a portion of tissue, wherein the catheter comprises a proximal section, a distal section, and a sheath coupled between the proximal section and the distal section, wherein the distal section comprises a tip with a plurality of optical ports disposed in a non-coplanar arrangement in the tip;
selecting at least one optical port of the plurality of optical ports as active for optical measurement;
acquiring optical measurement data from the portion of tissue using the selected at least one optical port of the plurality of optical ports in the catheter;
identifying one or more optical properties of the portion of tissue by analyzing the optical measurement data using a processing device coupled to the catheter; and
determining a time of denaturation of the portion of tissue based on the one or more optical properties of the portion of tissue.
