Arrangement and method for using lasers in laser plasma spectroscopy for material detection in moving parts which are statistically sequential

摘要

The invention relates to an arrangement and a method for laser-induced plasma spectroscopy with a laser having constant or freely triggerable pulse-succession frequency. The invention is distinguished in that an optical system is provided which directs the laser beam onto a part which is fed on a conveyor unit, so that the laser hits the same point on the part a multiplicity of times in succession.
