Keyword:  FZP扫描全息术高散射介质吸收体成像系统点扩散函数;
Abstract: 设计以菲涅耳波带板作为编码孔径的近红外扫描全息成像系统,并对该系统的点扩散函数进行了理论计算.结果表明:系统的点扩散函数接近理想的δ函数;实际测试了系统的点扩散函数,分析了实验结果与理论计算值存在差异的原因;用该系统对浓度为1%、深度为1.8 cm的intralipid脂肪乳剂中嵌埋直径分别为1.5 mm,1.0 mm和0.4 mm的金属丝做成的圆环进行了成像实验.实验结果表明:可较清晰地分辨直径1.5 mm和1.0 mm金属丝做成的圆环,对直径0.4 mm的金属丝做成的圆环也可识别.该系统用于高散射介质中吸收体成像具有较高的横向分辨力.
