Precise and fast determination of position and orientation, which is normally achieved by distance and angle measurements, has broad applications in academia and industry. We propose a dynamic three-degree-of-freedom measurement technique based on dual-comb interferometry and a self-designed grating-corner-cube (GCC) combined sensor. Benefiting from its unique combination of diffraction and reflection characteristics, the absolute distance, pitch, and yaw of the GCC sensor can be determined simultaneously by resolving the phase spectra of the corresponding diffracted beams. We experimentally demonstrate that the method exhibits a ranging precision (Allan deviation) of 13.7 nm and an angular precision of 0.088 arcsec, alongside a 1 ms reaction time. The proposed technique is capable of precise and fast measurement of distances and two-dimensional angles over long stand-off distances. A system with such an overall performance may be potentially applied to space missions, including in tight formation-flying satellites, for spacecraft rendezvous and docking, and for antenna measurement as well as the precise manufacture of components including lithography machines and aircraft-manufacturing devices.

双梳子光谱法解决了三自由度传感

通常通过距离和角度测量可以精确而快速地确定位置和方向，在学术界和工业界具有广泛的应用。我们提出了一种基于双梳干涉法和自行设计的光栅角corn立方（GCC）组合传感器的动态三自由度测量技术。得益于其独特的衍射和反射特性组合，可以通过解析相应衍射光束的相位光谱来同时确定GCC传感器的绝对距离，螺距和偏航角。我们实验证明该方法具有13.7 nm的测距精度（Allan偏差）和0.088 arcsec的角精度，同时反应时间为1 ms。所提出的技术能够在长距离的距离上精确，快速地测量距离和二维角度。具有这种总体性能的系统可能会应用于航天任务，包括紧密编队飞行的卫星，航天器的交会对接，天线的测量以及包括光刻机和飞机制造设备在内的组件的精确制造。
