1. An optical coherence tomography (OCT) imaging system comprising:

  • a source of broadband optical radiation coupled to a sample arm of the OCT imaging system;

    a beam shaping optical assembly in the sample arm of the OCT imaging system, the beam shaping optical assembly being configured to receive optical radiation from the source as a beam of optical radiation and to shape the spatial profile of the beam of optical radiation;

    a scan mirror assembly coupled to the beam shaping optical assembly in the sample arm of the OCT system;

    wherein the beam shaping optical assembly comprises a lens assembly configured to;

    change a numerical aperture (NA) of the OCT system without changing a focus of the OCT system;

    to change a focus of the OCT system without changing a NA of the system;

    orto change both the NA and the focus of the OCT system responsive to a control input; and

    an objective lens assembly coupled to the beam shaping optical assembly.
