Abstract

Official abstract text for this publication.

In certain embodiments, a device for optical coherence tomography (OCT) includes a signal detection device and a computer arrangement. The signal detection device is designed to detect an interference signal (G(ω)) for an object to be imaged in an optical frequency range (ω). The computer arrangement is designed to determine intermediate signals (G 1 (k), G 2 (k)) in a spatial frequency range (k) from the interference signal (G(ω)), whereby each of the intermediate signals (G 1 (k), G 2 (k)) is dispersion-compensated for a different depth (z 1 , z 2 ) of the object. A locally resolved image signal (FFT 1 , FFT 2 ) is determined for each of the intermediate signals (G 1 (k), G 2 (k)) by applying a Fourier transformation to the particular intermediate signal (G 1 (k), G 2 (k)). A tomography signal (G(z)) is determined from the image signals (FFT 1 , FFT 2 ).

First claim

Opening claim text (preview).

The invention claimed is: 1. A device for optical coherence tomography (OCT), comprising: a signal detection device designed to detect an interference signal (G(ω)) for an object to be imaged in an optical frequency range (ω), and a computer arrangement designed to calculate, for each depth of a plurality of different deaths (z 1 , z 2 ) of the object, association instructions (M 1 , M 2 ) that are adapted for the particular depth (z 1 , z 2 ) to the dispersion caused by the obj…
