在过去的10年中,利顿公司开发的零闭锁环形激光陀螺具有随机游走噪声低,刻度系数线性度高的特点。介绍的小型三轴陀螺完全继承了上述优点,它采用菱形12面体结构,能容纳具有正交敏感轴的三个非平面的环形激光光路,并采用双阳极单阴极激励来驱动三个轴,这种布局能大大减少元件的数量。另外,利顿还采用先进的镀膜技术来生产具有大入射角、极低损耗的增透膜。用一个反置镜片作为法拉第室,加以外置式磁铁,这就大大简化了三轴陀螺的结构。运用上述技术生产出的陀螺在体积、随机游走、刻度系数、分辨率、动态范围等特性方面都具有现有其它技术无法达到的水平,十分适用于下一代的定位跟踪系统。
In the past 10 years, Lycoming developed zero-lock ring laser gyro with random walk low noise, high linearity scale coefficient characteristics. The small three-axis gyroscope presented here fully inherits the above advantages. It uses a diamond-shaped 12-sided body structure that accommodates three non-planar ring laser paths with quadrature sensitive axes and dual anode single cathode excitation to drive three axes The layout can greatly reduce the number of components. In addition, Litton also uses advanced coating technology to produce AR coatings with large incident angles and very low losses. With a reverse lens as the Faraday chamber, with an external magnet, which greatly simplifies the structure of the three-axis gyroscope. The gyroscopes produced by the above technologies have the unobtainable levels of other existing technologies in terms of volume, random walk, scale factor, resolution, dynamic range and other characteristics, and are very suitable for next-generation positioning and tracking systems.
