A swept-source optical coherence tomography (SS-OCT) system with multiple sample arms was proposed and demonstrated. By connecting these sample arms and a typical SS-OCT system through an optical switch, which switched with a fast speed, multiple simultaneous real-time imaging was achieved. A prototype with two sample arms was presented. Both imaging performance is comparable to that of a typical SS-OCT system. By combining the results from two real-time operating arms, the multiplication of imaging field of view is realized with little additional hardware.
