摘要
用细激光束照明全息图是常用的一种再现方式,然而在文[1]以前,有关它的理论分析尚未见诸文献,而文[1]只给出了近轴情况下的物象关系,没有相应的实验,本文进一步分析了再现与记录时激光波长不同以及非近轴的更为普遍的情况,并进行了相应的实验,理论与实验相符甚好。近轴情况下的结果与文[1]一致。
Illuminating a hologram by a non-divergent narrow laser beam is an approach of reconstruction that holographer often abopt. However, prior to the thesis [1], the relating theoretical analysis of it has not yet been found in any technical literature, In the said thesis an analysis is made in the case that the hologram is illuminated by a narrow laser beam under the condition of paraxial approximation, and here the much more common phenomena in the case of non-paraxial condition is discussed, and the wave length of the illuminating laser beam is not the same as that of the recording laser. The theoretical result obtained agrees well with the experiment.
