We show that the two point intensity correlation in the near field of the scattered light is directly related to the two point density correlation g(r). Preliminary measurements on two sets of calibrated random pinholes of 140 and 300 &mgr;m diameters, and on aqueous solutions of latex spheres of 5, 10, and 40 &mgr;m are reported. A discussion on the desirability of the technique as a simple and powerful alternative to low angle scattering will be presented.
我们表明，散射光近场中的两点强度相关性与两点密度相关性g(r)直接相关。报告了对两组直径分别为140和300μm的校准随机针孔以及5、10和40μm乳胶球水溶液的初步测量结果。将对该技术作为低角度散射的一种简单而强大的替代方法的可取性进行讨论。
