体全息成像系统的深度分辨率特性分析

VHI recording with a spherical reference and a plane signal beams were introduced,and the total diffracted field intensity with displacement of the input point source (the probe source),away from a reference location in the direction x,y,z,was analyzed.The results show that the observed diffracted field obviously changes with the displacement in the direction z,and the observed diffracted field is suboptimal and spread on the detector plane with the displacement increase.The diffracted field intensity is nearly unchanged with displacement in the direction x,y.
