摘要： A probe for an optical coherence tomography system according to an embodiment of the current invention includes a sheath having a proximal end and a distal end and defining a lumen therein, an optical fiber disposed at least partially within the lumen of said sheath, and a sapphire lens attached to the distal end of the sheath to form a fluid-tight seal to prevent fluid from entering the lumen of said sheath. The optical fiber has an end arranged in an optical path with the sapphire lens to provide optical coupling between the sapphire lens and the optical fiber.

摘要： A beam diameter varying portion varies a first beam diameter of a measuring beam incident on an optical portion to a second beam diameter larger than the first beam diameter. An adjustment portion adjusts a condensing position of the measuring beam on the optical portion based on intensity information of a return beam from a position of an inspection object with the first beam diameter. The beam diameter is varied from the first to the second beam diameter by the beam diameter varying portion at the position adjusted by the adjustment portion to cause the measuring beam having the second beam diameter to be incident. A condensing position can be adjusted in a relatively short time because the measuring beam small in beam diameter is used, and a combined beam can be acquired with high transverse resolution because the measuring beam large in beam diameter is used.

摘要： A short coherence interferometer apparatus for measuring multiple axially spaced regions of a specimen, in particular the eye, which has at least one measuring beam path, through which multiple individual measuring beams are incident on the specimen, and one reference beam path, through which a reference beam runs, with which the individual measuring beams are superimposed and brought into interference. The individual measuring beams are axially offset to one another upon incidence on the specimen by an amount which is adapted to the axial spacing. The interferometer apparatus superimposes each individual measuring beam with the reference beam in an interfering manner and conducts it to a detector associated with the particular individual measuring beam. The individual measuring beams are combined into a mixture in which they have varying phasing in the superposition with the reference beam.

摘要： A dual beam low coherence interferometer with improved signal to noise ratio. The interferometer directs both a collimated beam about a focused beam to a target. A detector detects the multiscattering from the target with a splitter where a reference arm with matched mirrors allows for measuring both the intensity and magnitude values of the beam to be measured. The intensity and magnitude values indicate the imaging of the target in applications such as OCT(optical coherence tomography) having medical imaging applications, while improving the signal to noise ratios. Other applications include material characterization in ceramics, composites and other granular material. Additionally, the interferometer can be used to image target defects such as inclusions, voids, cracks, and the like, in ceramics and other materials which scatter light.

摘要： The disclosure relates to an optical system for inspecting an eye, having an OCT system which is configured to generate a measurement beam, which is incident on an object region in a converging manner to form a measurement focus. The OCT system has a beam expander which is disposed along the measurement beam between the scanning system and the objective lens and generates an intermediate focus between the scanning system and the objective lens. The OCT system is configured to generate different values of a beam waist diameter of the beam waist by means of controlling the controllable beam expansion of the beam expander. At the different values of the beam waist diameter, an axial beam waist position of the beam waist is substantially identical.

摘要： Monolithic beam-shaping optical systems and methods are disclosed for an optical coherence tomography (OCT) probe that includes a transparent cylindrical housing having asymmetric optical power. The system includes a transparent monolithic body having a folded optical axis and at least one alignment feature that supports the end of an optical fiber adjacent an angled planar end wall. The monolithic body also includes a total-internal reflection surface and a lens surface that define object and image planes. Light from the optical fiber end traverses the optical path, which includes the cylindrical housing residing between the lens surface and the image plane. Either the lens surface by itself or the lens surface and the reflective (eg, TIR) surface in combination are configured to substantially correct for the asymmetric optical power of the cylindrical housing, thereby forming a substantially rotationally symmetric image spot at the image plane.
