Abstract

An overlapping optical field (OOF) technique is developed to transform an optical field of Gaussian intensity into one with one-dimensional uniform intensity. The theoretical analysis and detected results demonstrate that one-dimensional uniform optical field with efficient utilization of optical energy can be obtained using the OOF technique. An experimental system for realizing the OOF principle is given, and the experimental results about the particle sizing and velocimetry are shown.
