Use laser to measure girder deflection

In engineering practice, there are often required to carry out the measurement of beam, girder or plate deflection in a short time in a few chosen points. Traditional methods, based on the measurement by dial gauges, inductive or surveying methods, require the commitment of the team, need expensive and complicated equipment and are time consuming. The paper presents a new, simple way to measure deflection of selected items using the device DKKZ-2010, which uses a laser light source.
