    Abstract: Apparatus for obtaining depth profile information from a transparent object, includes a confocal scanner for producing an en-face image of the object in an x-y plane, a spectral optical coherence tomography (OCT) apparatus for producing an OCT scan along at least one line in the z direction passing through a point in the x-y plane, and a display device. A processing unit displays on the display device the en-face image and an indication of the position of the point so as to permit the location of the OCT scan to be determined on the en-face image. In other embodiments, SLO and OCT images are produced from a common aperture, and spectral OCT images are produced simultaneously with fluorescence images.

    Abstract: OCT cross section images of a part of a curved object are displayed by creating a series of image points and placing each image point into a corrected image in such a way that the positions of scattering points within the image coincide with or are at least closer to their real spatial distribution within the curved object.

    Abstract: In an OCT apparatus, an object light beam is returned from a target and interferes with a reference light beam. Image information is obtained from a depth Z in the target that depends on the optical path difference between the object and reference beams with a resolution that depends on the coherence length of the light. A scanner transversely scans the target with the object beam over a plurality of image points defined by the resolution of the apparatus. Interface optics directs the reference and object beams onto an array of detector elements such that the optical path difference between the reference beam and the object beam varies across the array. The reference beam and the object beam interfere with each other over the array of detector elements for individual image points on the target during each transverse scan. A memory stores a subset of data points corresponding to each individual image point obtained from each detector elements of the array. A processor processes one or more of the subsets of data points to derive image information extending over a range of depths in the target for each individual image point. The obtained image information is displayed on a displace device.

    Abstract: A method of determining the external three dimensional external contour of a curved object in one step, which produces and processes a single composite en-face OCT image (a C-scan), which involves generating and processing a set of two dimensional image contours of the object in different image planes using a plurality of optical path differences in an OCT system with all such contours present in the the composite en- face OCT image. The image planes have a known spatial relationship with each other. The three dimensional external contour of the curved object is computed from the two dimensional contours in the composite en- face OCT image and the known spatial relationship between the image planes. Axial position and tilt of a sample are evaluated using an optimum shape object attached to the sample in one step, by processing as composite en- face OCT image generated by using a plurality of optical path delays.
