    Abstract: An optical coherence tomography (OCT) system including a source of broadband optical radiation and a beamsplitter coupled to the source is provided. The beamsplitter divides the source radiation into a reference path and a sample path. The reference path includes an optical switch to switch the reference path between a first path having a first reference reflection at a first reference optical path length and a second path having a second reference reflection at a second reference optical path length. The system further includes a beam combiner that mixes source radiation reflected from a subject in the sample path with source radiation returned from the first reference reflection and the second reference reflection. A detection system detects a first wavelength dependent interferogram during the first time interval and a second wavelength dependent interferogram during the second time interval. A processor preconditions the first and second wavelength dependent interferograms.

    Abstract: Optical coherence tomography (OCT) imaging systems are provided including 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, 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; and objective lens assembly coupled to the beam shaping optical assembly. The beam shaping optical assembly includes a lens assembly configured to change a NA of the OCT system without changing a focus; to change a focus of the OCT system without changing a NA of the system; or to change both the NA and the focus of the OCT system responsive to a control input.

    Abstract: Surgical microscopes are provided including at least one ocular, an objective lens; a collimated space between the at least one ocular and the objective lens; an illumination system optically coupled into the collimated space of the surgical microscope, wherein an illumination from the illumination system is directed along a path at least partially contained within the collimated space of the surgical microscope and through the objective lens; and one of a field diaphragm and obscuration mask positioned within the illumination system, and outside of a field of view of the at least one ocular, wherein the one of the field diaphragm and the obscuration mask blocks, attenuates or diverts rays from the illumination system that reflect from a surface of the objective lens such that the reflected rays are not visible through the at least one ocular.
