Abstract
The ensemble of spherical absorbing microparticles is illuminated by collimated beam of coherent light. The lights wavelenght is as little as diameter of any particle. Fourierlense forms in the focal plane spectrum pf spatial radiation scattered by microparticies. The intensity distribution of spatial spectrum, exept for the central part, is registered by multy-element photo-detector. If photo-detector is a set of concentric rings the signal from each photo-sensitive rinq is proportional to average light intensity. Registered reading of average intensity as function from ring radius are processed by computer. Further the algorithmes of processinç of the tneasurincj data are given.
