【摘要】：由于很多實(shí)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(jià)值。文中利用GS算法設(shè)計(jì)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(tái)階數(shù)量對(duì)該波段相位板整形結(jié)果的影響。對(duì)不同傳輸距離進(jìn)行了仿真計(jì)算,并在實(shí)驗(yàn)中將熱釋電相機(jī)PyrocamⅢ作為實(shí)驗(yàn)中的探測(cè)器對(duì)不同傳輸距離進(jìn)行了實(shí)驗(yàn)。實(shí)驗(yàn)結(jié)果表明,實(shí)驗(yàn)結(jié)果與仿真計(jì)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，
