Spatial shift detection arrangement for construction parts and structures

摘要

The arrangement includes at least one optical shift monitor with a light source (16), which emits optical radiation onto a curved mirror (11) at the location (X,Y,Z), which is to be measured. The direction of the reflected beam changes with the shift the object (1). At least one sensor is provided for the reflected beam for determining the direction of change. Preferably, the curved mirror is a concave mirror and an optical lens system (17) is provided between the light source and the mirror.
