Abstract
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(), G()) in a spatial frequency range (k) from the intermediate interference signal (G(ω)), whereby each of the intermediate signals (G(), G()) is dispersion-compensated for a different depth (z, z) of the object. A locally resolved image signal (FFT, FFT) is determined for each of the intermediate signals (G(), G()) by applying a Fourier transformation to the particular intermediate signal (G(), G()). A tomography signal (G(z)) is determined from the image signals (FFT, FFT).
