美国加州的Litton Systems公司的G.J.Martin提出环形激光陀螺仪的方案。这种陀螺仪可测量三个互相垂直轴的旋转。陀螺仪由三维框架和外部结构组成。外部结构是由菱形12面体的平面构成。在框架内,由三个互相正交非平面腔平面构成。在框架内形成三个互相正交的非平面腔。根据法拉弟效应,产生非反向分束光,使在三个平面中每个 G.J.Martin, Litton Systems, Inc. of California, USA, proposes a ring laser gyroscope solution. This gyroscope measures the rotation of three mutually perpendicular axes. The gyroscope consists of a three-dimensional frame and an external structure. The outer structure is made up of a rhombic 12-sided body plane. Within the framework, it consists of three mutually non-planar orthogonal cavity planes. Three non-planar cavities are formed in the frame orthogonal to each other. According to the Faraday effect, a non-inverse beam splitter is generated, making each of the three planes
