Paper Abstract

We present a simple and effective method of reducing the background noise of a full-field optical coherence tomography system that improves the image quality of the system. The system is based on a modified Michelson interferometer providing such new features as a tilted cubic beam-splitter and a spatial filter incorporated in the back focal plane of an imaging lens. The new arrangement reduces background noise significantly. The effects of the tilted beam-splitter and spatial filter on the optical image are also studied, and experimental results are provided.
