Abstract
A simple identification method of theodolite axes is presented. By directing a laser beam along the theodolite optical axis a diffraction figure of the cross hairs is generated. An analysis of the figure reveals the main and secondary axes. Interferential alignment is also used for precise identification of the optical axis. This method is easily applied by visual inspection. It is simpler than conventional methods used in surveying.
