Improvement of 200 kHz optical beam scanner performance with multiple internal reflection

The authors have realised a KTa(x)Nb(1−)(x)O(3)-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 mo...

Description
Summary:The authors have realised a KTa(x)Nb(1−)(x)O(3)-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.
