Abstract

We report a novel technique in which by optimum wavelength combination from dual broadband optical sources obtains a short coherence length for use in optical coherence tomography (OCT) systems. Another advantages of this technique lie in the ability to identify correctly the center fringe position, as a result, such as position, displacement or an absolute phase measurement over a large operating can be achieved. Theoretical analysis, computer simulations, and experimental verifications have shown that these techniques are able to increase greatly the dynamic range of the measurement under a low signal-to-noise ratio environment.
