FIELD: physics. ^ SUBSTANCE: device is a self-contained system for collecting information on fatigue changes in structures and has a device for picking up data, optically connected to the analysed object, and an image analysing system, which is a computer. The device for picking up data is portable and includes a sensor unit, a control unit, a memory module, an imaging module and a module for connection to the computer. The sensor unit includes a self-contained light source, a unit for adjusting light, unit for adjusting image sharpness, a prism system which is placed in such a way that, the analysed surface is illuminated perpendicular to it, a lens system which is designed for obtaining a magnified image of the analysed object, and a self-contained power supply. ^ EFFECT: increased accuracy of obtaining information, increased information content of results, reduced labour input. ^ 2 dwg |
