Abstract: Scanning optical beam imaging systems for imaging extended structures of an eye and providing biometry of an eye are provided. The systems include a focal system for shifting the focus of the scanning system from the front to the back of the eye. The systems provide for converging rays that can scan through the pupil of the eye, enabling scanning of the anterior and posterior segments of the eye using a common objective and a fixed working distance.

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 reflector at a first reference optical path length and a second path having a second reference reflector at a second reference optical path length, different from the first 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 reflector during a first time interval and the second reference reflector during a second time interval. 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; multiples the first preconditioned wavelength dependent interferogram and the second preconditioned wavelength dependent interferogram; and computes a first A-scan from the first wavelength dependent interferogram; a second A-scan from the second wavelength dependent interferogram; a spatial offset between the first and second A-scans derived from the multiplicative product of the preconditioned first and second wavelength dependent interferograms; and a combined A-scan from the first and second A-scans.

Abstract: Some embodiments of the present inventive concept provide optical coherence tomography (OCT) systems for integration with a microscope. The OCT system includes a sample arm coupled to the imaging path of a microscope. The sample arm includes an input beam zoom assembly including at least two movable lenses configured to provide shape control for an OCT signal beam; a scan assembly including at least one scanning mirror and configured for telecentric scanning of the OCT signal beam; and a beam expander configured to set the OCT signal beam diameter incident on the microscope objective. The shape control includes separable controls for numerical aperture and focal position of the imaged OCT beam.
