Embodiment Construction

[0056] 1. Optical coherence tomography device

[0057] figure 1 A schematic diagram showing an example of an optical coherence tomography apparatus, also referred to below as an OCT apparatus, having an interferometer 10 comprising a beam splitter 11, an illumination arm 12, a reference arm 13, a sample arm 14 and detector arm 15 . Furthermore, a radiation source 21 is provided for generating light which is filtered by an optical filter 22 and focused by an optical system consisting of lenses 23 and 24 onto an input region 25 of a light guide 26 . The radiation source 21 together with the optical filter 22 forms an arrangement also referred to as light source 20 .

[0058] The light coupled into the light guide 26 is coupled into the illumination arm 12 of the interferometer 10 via an optical system 28 located in its output region 27 . From there the light first reaches a beam splitter 11, through which it is on the one hand forwarded into a reference arm 13 and reflected b...

Abstract

The invention relates to a method and a corresponding system for optical coherence tomography, wherein at least two two-dimensional initial images of an object are recorded by means of an optical coherence tomography device in planes of the object which are spaced apart from one another, in particular run parallel to one another. (S), wherein the initial images respectively include a plurality of initial image values. In order to guarantee as reliable an object examination as possible, especially in the case of medical applications, an interpolation is performed in three-dimensional space on the initial image values ​​of the at least two two-dimensional initial images (S), wherein the resulting two-dimensional final image (S) is obtained ') interpolated value.

Description

technical field [0001] The invention relates to a method for optical coherence tomography and a corresponding system. Background technique [0002] Optical coherence tomography (OCT) is a method used to measure samples that scatter light within them. Biological tissue is particularly suitable for diagnostic examinations by means of OCT due to its light-scattering properties. Since OCT can cope with a relatively small light intensity and the wavelength of light used is mostly in the near-infrared range (750nm to 1350nm), OCT does not represent a radiation burden on biological tissues unlike ionized X-ray diagnosis. OCT is therefore of particular importance in medicine and is roughly comparable to ultrasound diagnosis, in which light is used instead of sound in the case of OCT. The travel time of the reflected light at different interface layers in the sample is detected by means of an interferometer. Utilizing OCT is typically aimed at achieving a resolution two orders of ...
