摘要

    摘要
  • 摘要: 设计并开发了光纤扫描式激光光斑测量仪。光纤探头采用逐行扫描的方式对激光光斑进行扫描，采集的光信号经能量转换、数据采集，最终传输到电脑，再由软件绘制出光斑图像。针对于大口径、脉冲激光光斑的测量提出了一种快速扫描的方案，并在此基础上计算分析了仪器的测量精度和测量时间这两个重要参数。与CCD摄像法进行了对比实验研究，结果表明：相对于CCD摄像法会受到接收屏的散射及成像系统误差带来的影响；此设备采用直接测量的手段，能够更加准确地获得光斑的实际尺寸以及光斑能量的空间分布。应用该仪器成功地进行了聚焦光束传输质量的测量。
    Abstract: A device for measuring the laser facula based on the fiber-scanning was demonstrated. The laser facula was detected by a fiber probe in a progressive scanning way. The light signal was converted, measured and transmitted to computer, then finally plotted by software. A fast scanning measuring scheme was proposed and two important parameters including measurement resolution and time were calculated and analyzed based on the large diameter pulsed laser measurement. A contrast experiment with CCD photographic method was done, and the result shows that this device avoids the effect generated by the scatter of receiving screen or imaging system deviation, it uses a directly measuring way and provides a better measurement result. This device is successfully applied to the measurement of focused beam transmission.
