1. An apparatus, comprising:
a catheter comprising a lens,
the catheter disposed within a strain-sensing sheath such that the lens rotates and translates within the strain-sensing sheath;
a strain-sensing system optically coupled to the catheter; and
a controller coupled to the strain-sensing system,
the controller, using the strain-sensing system, configured to:
determine a first strain of the strain-sensing sheath at a first location based on fluorescence spectroscopy of a first strain-sensing molecule associated with the strain-sensing sheath, and
determine a second strain of the strain-sensing sheath at a second location based on fluorescence spectroscopy of a second strain-sensing molecule associated with the strain-sensing sheath,
the first location being different from the second location, and the controller further configured to:
determine a catheter curvature of the catheter between the first location and the second location based on determining the first strain and the second strain of the strain-sensing sheath.
