    摘要: A spectroscopic instrument includes a first optical component for spatial spectral splitting of a polychromatic beam of light impinging onto the first optical component, an objective, which routes various spectral regions of the split beam of light onto differing spatial regions, and a sensor, situated downstream of the objective in the beam path of the beam of light, with a plurality of light-sensitive sensor elements. The sensor elements are arranged in the beam path of the split beam of light in such a manner that each sensor element registers the intensity of a spectral sector of the beam of light and the medians of the spectral sectors are situated equidistant from one another in the k-space, where k denotes the wavenumber.

    摘要: An optical coherence tomography device comprises a light generator, a dispersive medium, an optical coupler and a detector. The light generator is adapted to generate a series of input pulses of coherent light, each input pulse having an input pulse width. The dispersive medium has an input that is optically coupled to the light generator and an output for output pulses. The dispersive medium is adapted to stretch the input pulse width to an output pulse width of each of the output pulses by chromatic dispersion. The optical coupler is adapted to couple the output pulses into a reference arm and a sample arm. The optical coupler is further adapted to superimpose light returning from the reference arm and the sample arm. The detector is adapted to detect an intensity of interference of the superimposed light with a temporal resolution of a fraction of the output pulse width.

    摘要: In a process for optical coherence tomography a plurality of first OCT slice images, in each first slice image representing a different slice of an object, are recorded. Subsequently a reference figure that is representative of the three-dimensional contour of at least one structural feature of the object in a given three-dimensional coordinate system is ascertained by feature recognition of the at least one structural feature in the first slice images. Then a plurality of second OCT slice images, each second slice image representing a different slice of the object, are recorded. At least a fraction of the second slice images are displaced in the coordinate system until each second slice image is in feature overlap with the reference figure. Lastly, a set of three-dimensional OCT image data is generated at least from the feature-overlapped second slice images.
