SLODAR method. Part 1: Development of a method for the determination of the positions of optical elements


The principle possibility for the use of the SLOpes Detection And Ranging (SLODAR) method for the determination of the positions of optical elements is demonstrated. The results of a numerical simulation are presented; they provide the possibility of using the correlation function of the local wave front slopes of two reference radiation sources for the determination of the positions of one or a few phase screens. The simulation results are shown to qualitatively and quantitatively agree with the experimental results. A modification of the method to allow for the determination of the positions of thick optical elements (such as lenses) is discussed.
