介绍了一种基于反射光栅和高速线阵图像传感器实现宽波段、脉冲激光波长测量的设计方案;对强太阳光背景下信号的提取进行了理论分析,给出了激光功率密度、灵敏度信噪比和分辨率的计算公式;以ZEMAX软件进行了系统仿真,为元件选型提供了技术保障理论分析与系统仿真结果表明,该方案可以对远场短中进行测试.
Principle of coherent detection of wide spectrum and pulsed laser wavelength is introduced based on a reflection gate and a high speed linear detector. Signal detecting method is theoretically discussed in the strong sun shine. Formulas for calculating the laser power, sensitivity, S/N ratio and wavelength resolution are also given. ZEMAX is used to simulate the system, providing the guides for elements selection. Theoretical analysis and system simulation show that it is feasible to measure far and short pulsed laser wavelength with this project.
