Abstract: An inspection device for contactless three-dimensional inspection of a blade for a turbomachine. The device includes at least one first pair of laser measurement modules to scan the blade and a rotational drive to rotate, about the main axis, the blade relative to the modules along the main axis of the blade. The device then rebuilds a three-dimensional virtual representation of the blade using data coming from the scan and performs a dimensional inspection using the three-dimensional representation. Each pair of modules includes a first module oriented towards a first face of the blade and a second module oriented towards a second face of the blade. The modules are oriented relative to the blade so that during rotation, the modules scan the faces of the blade on the entire rim of the blade, and during translation of the blade along the main axis, the faces are scanned throughout their height.

Abstract: An inspection device for contactless three-dimensional inspection of a circular, mechanical component with toothing having a main axis of rotation. The device is configured to scan the teeth by at least one first pair of laser measurement modules and rotationally drive the component about the main axis relative to the laser measurement modules. The device then rebuilds a virtual three-dimensional representation of the component using data coming from said scanning and performs a dimensional inspection using the three-dimensional representation. Each pair of modules includes a first module oriented towards a first face of a tooth and a second module oriented towards a second face of a tooth. The modules are oriented relative to the component so that during a rotation of the component, the laser measurement modules scan the first and second faces of each tooth throughout their thickness and depth.
