摘要
根据信息论的基本原理 ,从平面全息系统成像全过程的一般方程出发 ,利用回转椭球波函数以及平面全息系统的自由度表达式 ,对在实际工作中粒子场全息测量可能遇到的几种实验记录系统进行了分析计算 ,得到了相应的系统成像自由度的大小。同时根据信息匹配的原则 ,给出了粒子场所能成像的物场范围。比较了各种构型全息系统的信息量的大小 ,并进行了简要讨论。
The paper is based on the basic principle of the information theory By using the prolate spheroidal wave function and the free degree expression of the plane holographic system and it's normal imaging equation , several types of recording system in particles holography measurement are analyzed The free degree and the range of object imaging are obtained Meanwhile, the information capacity of the systems are also discussed
