Circular-ranging OCT methods overcome data bandwidth barriers to high-speed and long-range laparoscopic imaging. As such, the beam-scan engine within the laparoscopic probe has become the critical speed and field limiting component within these systems. MEMs devices are an attractive strategy for beam-scanning but they offer limited scan fields when operated at high speeds. We demonstrate a high-speed and large-field MEMs-scanner-based laparoscopic probe based on a parallelized 32-beam design. The design and performance of this laparoscopic probe are presented, and volumetric OCT imaging at near video-rate speeds is demonstrated.
