我们提出了一个强大的光学滚动传感器具有高动态范围和高吞吐量的能力。其工作原理依赖于跟踪光学方波编码光源的振幅。在将方波编码到偏振参考上之后，偏振光的正交解调允许我们消除共模噪声。该传感器的优点包括简单、低成本、高通量、对源振幅波动不敏感以及无固有漂移。在这封信中，我们介绍了工作原理，并通过实验验证了43度的可用工作范围和0.002度的分辨率。该传感器具有最高的动态范围的光学辊感测。(C)2015年美国光学学会
We present a robust optical-roll sensor with a high-dynamic range and high-throughput capabilities. The working principle relies on tracking the amplitude of an optical square wave-encoded light source. After encoding a square wave onto a polarization reference, quadrature demodulation of the polarized light allows us to cancel commonmode noise. Benefits of this sensor include its simplicity, low cost, high-throughput, insensitivity to source amplitude fluctuations, and no inherent drift. In this Letter, we present the working principle and experimentally validate a 43 degrees usable working range with 0.002 degrees resolution. This sensor has the highest reported dynamic range for optical roll sensing. (C) 2015 Optical Society of America
