【摘要】：由于很多实际应用中需要光斑环形分布,因此太赫兹高斯光束整形环形光束的研究具有重要的理论和应用价值。文中利用GS算法设计相位板,将太赫兹波段的高斯光束整形为环形光束。讨论了刻蚀台阶数量对该波段相位板整形结果的影响。对不同传输距离进行了仿真计算,并在实验中将热释电相机PyrocamⅢ作为实验中的探测器对不同传输距离进行了实验。实验结果表明,实验结果与仿真计算结果接近。
[Abstract]:Due to the fact that the circular distribution of light spot is needed in many practical applications, the research of terahertz Gao Si beam shaping annular beam has important theoretical and practical value. In this paper, the GS algorithm is used to design the phase plate, and the Gao Si beam in terahertz band is shaped into a ring beam. The effect of the number of etching steps on the shaping results of the phase plate is discussed. The different transmission distances are simulated, and the pyroelectric camera Pyrocam 鈪，
