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。 According to the basic theory of information theory, based on the general equation of the whole imaging system of plane holography, several experiments that may be encountered in the field of holographic particle measurement are carried out using the rotational ellipsoidal wave function and the degree of freedom expression of the planar holographic system. The recording system was analyzed and calculated, and the corresponding degree of freedom of system imaging was obtained. At the same time, according to the principle of information matching, the range of object field that can be imaged by particle sites is given. The amount of information in each configuration holographic system is compared and discussed briefly.
