摘　　要：为了满足激光系统实战条件下的快速检测分析和保障维修的需要,采用宽光谱响应的面阵CCD成像器件和图像采集卡作为图像采集硬件,利用Visual C++6.0和Matlab混合编程设计图像采集分析软件,利用该系统开展了脉冲激光图像现场采集的相关实验,并对采集图像进行了快速分析和可视化显示。多次实验结果表明,该方法可实现对纳秒激光光斑图像的实时有效采集,结合分析软件可实现对采集图像的快速处理和空间分布特性的三维立体显示,另外该软件还能通过分析图像提供信息对比度高、易于观察的伪彩色图像。该方法的研究为激光系统的检测维修和战场激光主动侦察的目标探测与识别提供了基础的技术手段。In order to meet the rapid detection and maintenance needs of the laser system in the actual battle field conditions, the image acquisition card and the array CCD imaging device with wide spectral band response were used as the imaging system hardware. The image acquisition and analysis software of the system was designed by mixed programming of Visual C＋＋6.0 and Matlab. The online acquisition experiment of the pulsed laser image was done with the system. The system can be used to speedy analyse and show the laser image. Several experimental results demonstrate that this method can collect the nanosecond laser spot effectively of real-time images. With the analysis software, the image can be processed rapidly and the spatial distribution can be shown in three-dimensional shape. The analysis software can also provide pseudo-color image with high contrast, which was easy to observe. It lays the foundation for the detection and maintenance of the laser system, the target detection and recognition of the active reconnaissance.
