摘要
A modified Ronchi test with an extended source is presented. By the use of a matched pair of source grating and Ronchi grating, a pure shearogram between two shifted wave fronts is obtained, and the extra interference with other disturbing grating orders is largely suppressed by the use of a specific grating layout.
