A computer-implemented method for simulating a response from a fluence test card (3) to a laser device (5) is presented, comprising selecting shot pattern information (101i); reading aperture information (103i); reading laser power information (105i); calculating or calling a mathematical model (M); determining a fluence distribution (100) from the shot pattern information (101i) and the laser power information (105i) using the mathematical model (M); and providing the determined fluence distribution (100). Furthermore, a method for determining and displaying at least one fluence distribution (100) and a data processing device (91) for performing these methods, as well as a computer program product and a data signal, are described. Finally, a fluence test device (1) and a laser processing system (5) for performing the methods are presented.

The invention refers to the fields of materials science and metrology and relates to calibration bodies as usable in analytical spectroscopy, for example. The problem addressed by the present invention is therefore that of producing electrically conductive calibration bodies, in particular for calibration of hydrogen measurement devices. The calibration bodies can be provided in large numbers, easily and inexpensively. The problem is solved by calibration bodies, in particular for calibration of hydrogen measurement devices, at least consisting of an electrically conductive porous sintered body, with an essentially homogeneous distribution of pores and / or defect sites, for example dislocations, stacking defects and / or twinned structures, in the sintered body, in which an adjustable hydrogen concentration is present depending on the number and size of the pores and / or defect sites in the sintered body, wherein the hydrogen is in physically and / or chemically bonded form in and / or at the surface of the pores and / or defect sites, and wherein the set hydrogen concentration in the calibration body decreases in the amount specified in each case over time.
