SLODAR technique. Part 2: the use of point sources.
In this paper SLODAR (SLOpes Detection And Ranging) technique is added by the a novel theory, able to locate aberration layer positions for the case of using the point references, source having converging/diverging wavefronts. The relation between the correlation peak displacement and the distance to the measured aberration layer, as well as the measurement error and maximal measured distance to layer are determined in this paper. The numerical experiments are carried out to determine locations of single and multiple phase screens in conditions close to experimental.
