Abstract

This paper describes measuring and aligning segmented mirrors with Point Diffraction Interferometer (PDI). It discusses how to use the different coherent lengths of the selected light sources to simplify the piston error adjustment process. It addresses the theory behind the experiment, models the experimental setup, analyzes the data, and discusses the result. The procedure of using PDI to adjust the piston error is provided.
