Optical technique for particle measurement.
A novel overlapping optical field technique that transforms an optical field of Gaussian intensity into one with uniform intensity is described. Comparison of calculated and measured results demonstrates that a highly uniform optical field in one transverse dimension with efficient utilization of optical energy can be obtained by using the overlapping optical field technique. This technique can be used for particle sizing and velocimetry.
