Paper Abstract

The optical coherence tomography (OCT0 is a novel imaging technique for producing high-resolution cross-sectional images of the internal microstructure. Resolution improvement is an important task in the OCT. A new approach is proposed for achieving shorten coherence length by combining several low coherence sources to improve the resolution of the OCT. This optimization synthesis problem belongs to solving an inverse source problem. An optimization algorithm is used to select the parameters of sources for decreasing the effective coherence length and inhibiting side lobe simultaneously. Computer simulations are presented to approve our method. By combining three light sources, the coherence length can be reduced to 57% of the smallest one of a single source used and the side lobes are lower than 5% of the center packet.
