A system for providing intraoperative feedback to a user during the course of surgery. A core imaging unit provides low-coherence optical radiation coupled to a sampling device and generates optical coherence tomography (OCT) data based on combining scattered light received from the sampling device together with a reference signal. The sampling device is adapted to receive the low-coherence optical radiation from the core imaging unit and to illuminate the tissue, and to collect light scattered by the tissue and to return said light to the core imaging unit. A core software unit receives the OCT data from the core imaging unit provides real-time feedback, such as an image, to the user.
