Abstract
A method based on moiré deflectometry for direct determination of the number of transverse modes of radiation of a light beam is presented. An expression for the number of transverse modes of a light beam, as a function of the beam divergence, is derived. We demonstrate the method for a Cu-vapor laser-beam analysis.
