摘要：

Two-dimensional angular optical scattering (TAOS) is recorded for several particle shapes and configurations. A lens is used to collect a large solid angle of the light and transform the angular profile into a planar distribution according to the Abbe sine condition. Qualitative agreement is found between experiment and theory for the TAGS from spheroids having the same aspect ratio but different sizes. A distinctive irregular island structure is observed in the TAGS from clusters of Bacillus subtilis spores and polystyrene latex spheres. The density per solid angle of these islands is found to increase with cluster diameter. (C) 1998 Optical Society of America.
