Abstract

A three-phase shifting method is introduced to spectral OCT to eliminate mirror image and autocorrelation noise inherent in spectral OCT signal, thus improves the measurable range of spectral OCT by a factor of 2. The feasibility of such method is demonstrated using a mirror like object. Comparison between two-phase and three-phase shifting methods is performed using a 1mm slab as the object. An intact porcine cornea tissue in vitro is also used to show the potential of this method for biological imaging.
