ABSTRACT:
A method is disclosed for calibrating an optical measuring system (14, 18, 0, 22) of the type which reproducibly projects a beam of light (16) over an extended period of time. The deviation between an incident beam and a rerflected beam is measured on both sides (30, 32) of a parallel-sided calibration mirror (28).
