【摘要】：由于很多實際應(yīng)用中需要光斑環(huán)形分布,因此太赫茲高斯光束整形環(huán)形光束的研究具有重要的理論和應(yīng)用價值。文中利用GS算法設(shè)計相位板,將太赫茲波段的高斯光束整形為環(huán)形光束。討論了刻蝕臺階數(shù)量對該波段相位板整形結(jié)果的影響。對不同傳輸距離進(jìn)行了仿真計算,并在實驗中將熱釋電相機PyrocamⅢ作為實驗中的探測器對不同傳輸距離進(jìn)行了實驗。實驗結(jié)果表明,實驗結(jié)果與仿真計算結(jié)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，
