Abstract:

A fast-scan-rate swept laser for optical coherence tomography OCT is suitable to record and analyze a 3-D image volume. However, the whole OCT system speed is limited by data streaming, processing, and storage. In this case, post processing is a common technique. Endoscopic clinical applications prefer onsite diagnosis, which requires a real-time technique. Parallel digital signal processors were applied to stream and process data directly from a data digitizer. A real-time system with 20-kHz axial line speed, which was limited only by our swept laser scan rate, was implemented. To couple with the system speed, an endoscope based on an improved 3-D microelectromechanical motordiameter 1.5 mm, length 9.4 mm was developed. In vivo 3-D imaging of the human airway was demonstrated.
