【摘要】 提出了一种基于傅里叶变换的光谱识别激光告警方案,以光纤式平行光方向变换器为光学天线,以实心静态等效斜楔干涉具为相干元件,通过线阵CCD光电转换和傅里叶变换后得到激光光谱信息。文中详细分析了该方案的设计方法和关键部件的结构及原理,构建了实验系统,进行了相关的性能分析。实验结果表明:应用该系统对7个半导体激光器波长的测量,平均误差为3.3472nm,满足10nm的波长分辨力指标。更多还原

【Abstract】 In order to real-time and reliably detect the types and character parameters of hostile incident pulse laser (HIPL),a kind of spectral discriminating laser warning system which based on Fourier transform was brought forward.The optic fiber direction converter of parallel light was used as optic antenna,a static and solid Fourier transform modified wedge interfering etalon was used as coherent element,the spectrum information was obtained after the Opto-Electronic transform by liner charge couple device (CCD) and Fourier transform. The design method and the structure principle of key parts were analyzed detailedly in this paper,it also consisted the correlative performance analyze and setting up of experiment system.The result shows that the measure of wavelength of seven different semiconductor lasers,the average error is 3.3472nm,the target of wavelength resolving power meets requirement of 10nm.更多还原
