ABSTRACT:
The invention relates to a method for optical coherence tomography comprising the steps of:providing of a reference light beam and a measurement light beam,combining of the reference light beam and the measurement light beam to provide a combined light beam,modulating of the reference light beam,sampling of the combined light beam to measure an amplitude of an intensity variation for each sampling position,adding of the amplitudes to provide an intensity signal for one picture element.correcting deformations and aberrations either in the electronic, or in the optical domain
