Abstract: A testing device for carrying out investigations on a test body, which testing device comprises a rail guide with a slide unit coupled to a drive unit for acceleration, on which slide unit the test body is arranged, wherein the drive unit is connected to a control unit and at least one image capturing unit is provided for capturing image data of the test body. The at least one image capturing unit is arranged on a further slide unit, which is arranged on a further rail guide running parallel to the rail guide of the slide unit of the test body, wherein the further slide unit of the at least one image capturing unit comprises a separate drive unit for accelerating the further slide unit, which drive unit is connected to the control unit. Further, embodiments of the invention relate to a use of such a testing device.

Abstract: A device for investigating a test body, wherein the device comprises a mounting unit for fixedly mounting the test body during the entire investigation, an electric drive unit adapted for mechanically driving the mounting unit and the test body mounted thereon, and a control unit adapted for controlling the electric drive unit to accelerate the test body mounted on the mounting unit, wherein the device is adapted so that the mounting unit and the test body mounted thereon are mechanically driven exclusively by the electric drive unit, wherein the electric drive unit comprises an electric linear motor.
