摘要
The properties of diffraction focusing systems composed of a series of irises, coaxially distributed along a laser beam, are analyzed.Based on diffracted-ray methods, complete design equations and optimization procedures are given.Focusing experiments on a He–Ne laser beam are reported with two types of focusing structures, and the results are found to agree completely with the theoretical predictions.© 1979 Optical Society of America.
