Mehrskalig einsetzbares Messsystem für synchronisierte dreidimensionale Dehnungs- und Temperaturfeldbewertungen

TENDER DESCRIPTION

For spatially precise 3D deformation analyses with the highest possible detail resolution, the camera systems to be used (hereinafter also referred to as 3D measurement sensors) must enable an image resolution of at least 24 megapixels. For use in the deformation and temperature analysis of cyclically stressed specimens, the measurement system must additionally allow an image rate of at least 100 frames per second (at full image resolution). The interfaces between cameras and measurement computer must correspondingly support large data transfer rates (at least 10 GigE connection between camera and measurement computer). For multi-scale component analyses, the measurement system must be very flexibly configurable so that measurement field sizes can be realized per measurement sensor, with dimensions between 20 mm and 5,000 mm width or height. To this end, the measurement system must have the necessary interchangeable lenses as well as calibration objects and the associated additional hardware, such as tripods, lighting, adapters, etc. For deformation analyses on large-format components with measurement field sizes over 5,000 mm as well as for double- or multi-sided structural…
