Abstract- Optical Coherence Tomography (OCT), as a noninvasive imaging technique, has been widely applied in medical and industrial fields. The light source commonly used in OCT -Super luminescent diodes (SLD) - are partially temporally coherent light source, which usually exhibits typically the resolution of 10-20 μm. In this article, fabrication and calibration a visible spectral-domain OCT has presented. We show a good theory-experiment agreement for OCT signals as a function of depths. In order to Calibration the OCT, we investigated the thickness of cover slip which result show a good agreement with the outcome result of a digital micrometer. Because of low temporal coherence length of halogen lamp (1.6 μm) the axial resolution of the acquired images increased
