一、引言利用脉冲激光器而使陀螺马达获得高精度的闭环自动精密平衡已获成功。平衡转子的方法可分为点状平衡和弧状平衡两种。点状平衡即被平衡转子的转速V_r与旋转光路的转速V_(opt)相等的条件下进行相互作用,也就是类似于激光与静止物体的相互作用。弧状平衡相应于V_r>>V_(opt)的情况,或激光光束通过光学系统直接作用于旋转物体的情况。在这种方案中,相互作用的区段的长度取决于转子直径,转速及激光的振荡脉冲宽度。深度则取决于转 I. INTRODUCTION The use of pulsed lasers has enabled gyro motors to achieve high-precision, closed-loop, automated precision balancing. The method of balancing the rotor can be divided into two kinds of point balance and arc balance. Point-like balance that is balanced rotor speed V_r and rotating optical path speed V_ (opt) under the same conditions of interaction, which is similar to the laser and stationary objects interaction. The arc balance corresponds to the case of V_r >> V_opt, or the case where the laser beam directly acts on the rotating object through the optical system. In this scenario, the length of the interacting section depends on the rotor diameter, the speed of rotation and the oscillation pulse width of the laser. Depth depends on the turn
