Signal processing in OCT systems

The use of signal processing in optical coherence tomography (OCT) for the optical imaging of tissue was discussed. OCT was non-invasive technique in which low power was used for wavelengths in the therapeutic window 600-1300 nm. It was observed that for large image angular size, no external modulation was needed. The result shows the compromise between scanning speed and transversal pixel resolution when the carrier created by the XY-scanner was used
