Abstract
An efficient technique for constructing the achromatic phase shift in the reference arm of spectral-domain OCT is presented. The technique is based on a wavelength-dependent optical delay line using a diffractive grating as a dispersive element. The high value of mirror artifact decreasing is demonstrated in common OCT setup.
