中文摘要：
设计了基于GPIB总线的钠荧光激光雷达控制系统，实现了观测数据的实时采集控制及望远镜-发射光束联合调整；该方法通过调用GPIB接口函数设置光子计数器，并实时存储回波数据到控制电脑中；针对激光雷达联合调整中光学方法的不足，提出了单站式双轴收发分置结构激光雷达中发射光束最佳指向搜索方法，并采用数值滤波的方法提高了搜索精度；经验证该激光雷达控制系统工作稳定有效，降低了观测人员的工作强度，保证了钠层观测实验的顺利进行。
英文摘要：
lidar control system based on GPIB is proposed. Depending on this system, real-time data acquisition control and accurate telescope-transmitter alignment are implemented. The first object is achieved by the use of GPIB interface functions. With these functions, echo data are acquired and stored on PC automatically. For the shortage of optical telescope-transmitter alignment, an echo search method is presented, which is suitable for noncoaxial lidar system. Based on this method, transmitting light can point at the best observation position. And search precision is improved by digital filtering. These are tested by observation and adjustment of the Na- resonance fluorescence lidar of Wuhan University and proved to be effective and convenient.
