Paper Abstract

The method presented for evaluating size distributions of small objects makes use of the Fourier transformation performed optically by a lens. The objects are stored in a transparent photographic recording whose spatial frequency pattern (far field diffraction pattern) is investigated.The method is first tested with patterns of model objects and then successfully applied to real particles, namely photographs of small air bubbles in water.
