无马达环形激光陀螺仪可以减小体积,减轻重量、改善可靠性和节省费用,从而优于目前的环形激光陀螺仪,麻省诺伍德的诺思罗普公司精密产品部正对此进行试验。该陀螺仪的设计采用独特的光学和磁学结构,从而防止了称为“锁定”的主要陀螺误差源,同时不需要通常环形激光陀螺仪为防止这种误差所用的马达。由于消除了除其本身之外的唯一动运部件马达,因而提高了陀螺仪的可靠性、降低了制造成本,并可制造出较普通环形激光陀螺仪更小和更轻的无马达环形激光陀螺仪。诺思罗普 No-motor ring laser gyroscopes are smaller than today’s ring laser gyroscopes due to their reduced size, weight, reliability and cost savings, as is the case with Northrop Grumman Precision Products, of Norwood, Mass. The gyroscope is designed with a unique optical and magnetic structure that prevents the main gyro error source known as the “lock” and eliminates the need for the usual ring laser gyros to be used to prevent such errors. Eliminating the only mover motor other than itself increases the reliability of the gyroscope, reduces manufacturing costs, and enables the production of smaller and lighter, motorless ring laser gyroscopes than conventional ring laser gyroscopes instrument.
