DETERMINATION DEVICE FOR DETERMINING AT LEAST ONE PARAMETER OF AN ENERGY BEAM
First Claim
1. Determination device (2) for determining at least one parameter of an energy beam (4), in particular an energy beam (4) generated via an irradiation device of an apparatus (1) for additively manufacturing three-dimensional objects, which determination device (2) comprises two determination units (5, 6) arrangeable or arranged in succession in a beam path (3) of the energy beam (4), characterized in that each determination unit (5, 6) builds or comprises at least one complementary pattern element (15, 18, 21, 23, 24, 27, 30), wherein at least two pattern elements (15, 18, 21, 23, 24, 27, 30) of the two determination units (5, 6) complement each other so as to form a superordinate pattern (32, 35).
