| Abstract: | Complex spectral domain optical coherence tomography (OCT) system was established in order to improve the measurement range of complex multi-layer objects. Through reconstruction of images amplitude and phase, the noises and the qualities of images were degraded and enhanced,respectiely and it was proved by tests on the sample. The results indicate that the system can remove the parasitic terms and mirror images of spectral OCT, improve the resolution of the tomographic images, and the accessible depth range expands by a factor of 2 to realize the full range measurement. |
