摘要: 基于星光II实验装置进行了Gabor波带片编码成像探索性实验研究。采用束匀滑光斑三倍频激光打靶，辐照专门设计的ＣＨ埋金属条靶（共两种），产生了有明确形状、边缘清晰的等离子体。研制了专门的Gabor波带片编码相机，并利用该相机采用单张胶片对不同的靶目标在不同的深度层次上曝光的技术，获得了具有深度层次信息的三维激光等离子体编码像。利用数值重建技术对实验所获得的图像解码，最终获得了在不同深度层次上的激光等离子体信息。Abstract: Primary investigation of X-ray Gabor zone plate coded imaging was performed based on the Xingguang II facility. Special designed CH foil burying W thread targets was irradiated with 3ω0 Nd laser large spot smoothing radition to generate a certain shape Plasma and special developed binary Gabor zone plate encode holography camera was used the image it. Integrate two shots with placing target in different position in z direction one got holograms come from plasma with certain 3D structure. Typical hologram was decoded with numerical reconstruction technique. Expected result was obtained.
