Image processing in frequency domain for common path optical coherence tomography (CP-OCT)

CP-OCT is a single arm OCT technique which offer significant advantages over dual arm OCT. These techniques are used for presenting a cross sectional view of 3D structure and inner layers of the structure especially turbid in nature. Image processing is a major challenge in OCT instrumentation. This paper focuses on the imaging process on acquired power spectrum of the collected data from a novel optical fiber tip as a CP-OCT probe. Image enhancement techniques applied to these data sets improve the visualization of the image. The work is done by using image processing and signal processing toolbox of MATLAB vR2010. The purpose of this paper is only to show improvement in the visualization of the cross sectional image of a sample by applying mentioned techniques for advantageous CPOCT environment. Arbitrarily, cello tape is chosen as a sample as it contains more number of layers so that it will be easy to distinguish the visualization quality in the outcome images.
