【 摘 要 】
The authors have realised a KTa x Nb1â x O3-based optical beam scanner that has three- and five-pass configurations with internal reflection whose scanning angle is exactly proportional to the optical path length. They successfully increased the scanning angle to about 140 mrad with a 200 kHz modulation using a five-pass configuration. This beam scanner will provide an optical coherence tomography (OCT) system with a spatial resolution of 7 μm and advantages over other OCT systems.【 授权许可】
