采用球形电机作为光电成像跟踪转台的旋转机构，研究一种新型高集成度和超大视场的光电成像跟踪系统。针对球形转台的特殊结构和旋转特点，分析了转台在三维空间中进行螺旋式扫描的特性，并设计了相应的控制方法，采用实四元数组作为转台旋转控制的数据结构。仿真结果表明，球形转台可以按预先设置的参数进行旋转，避免了空间的漏扫。
採用毬形電機作為光電成像跟蹤轉檯的鏇轉機構，研究一種新型高集成度和超大視場的光電成像跟蹤繫統。針對毬形轉檯的特殊結構和鏇轉特點，分析瞭轉檯在三維空間中進行螺鏇式掃描的特性，併設計瞭相應的控製方法，採用實四元數組作為轉檯鏇轉控製的數據結構。倣真結果錶明，毬形轉檯可以按預先設置的參數進行鏇轉，避免瞭空間的漏掃。

Spherical motor is used for the rotatable part of the opto-electronic imaging tracking turntable in this paper,a new kind of opto-electronic imaging tracking system which has high integration and especially wide field of view is studied. Due to the special structure and rotating trait,the helical scan character of the turntable in the three-dimensional space is analyzed,and the corresponding control method is designed,meanwhile quaternion is used for the data structure of the turntable rotation. Simulation result shows that the spherical turntable could rotate according to the parameters which are set in advance,thus avoiding the missing scan in the space.
