Abstract

激光测月(LLR)具有测量距离远和回波光子少的特点,观测中需要适当更新回波探测器的位置以提高回波探测概率。采用现场可编程门阵列(FPGA)技术研制多步进电机同步控制系统,并结合VC++软件开发工具开发其计算机控制程序,最终实现回波探测器在xoy探测平面上位置的计算机控制。测试结果表明,两个步进电机可以各自单独运行或同时运行,使回波探测器可以单独沿着x轴或y轴移动,也可以同时沿着x轴和y轴移动,最小移动步长为2.5μm,实现对探测器位置的精准控制。

Other Abstract

Lunar laser ranging (LLR) has the characteristics of far measurement range and small number of return laser photons,so the position of detector receiving return photons should be adjusted properly during LLR observation to improve the detection success probability. Synchronization control system for multiple step motors is researched and realized with the technique of field programmable gate array(FPGA), and control interview program is developed with VC++ software developing instrument. Finally, computer control of the detector position is realized on xoy detecting plate. Test result indicates that two step motors can run separately or simultaneously,so that the detector could move along x axis or y axis alone, or along x axis and y axis at the same time.The minimal step length is 2.5 μm, which allows for precise detector position control.
