A sensor unit ( ), a device, and a process for inspection of a surface ( &Dgr;) of an object ( ) for the purpose of identifying surface characteristics, such as structural defects. The device contains an emitting module ( ) and a receiving module ( ). The emitting module emits at least one beam bundle ( &Prime;). The receiving module has at least one light receiver ( ). A rotating polygonal mirror wheel ( ) is located in the focal point of a parabolic mirror ( ). A beam bundle ( ) of the laser ( ) is directed onto the mirror ( ) by means of a telecentric lens, which guides the emitter and receiver beam on the same optical axis, whereby the parabolic mirror ( ) guides the deflected beam bundle ( &Prime;) under a constant angle relative to the axis of symmetry ( ) of the parabolic mirror ( ) along a scanning line ( ) over the object ( ). The diffusely reflected beam bundle, after being deflected out of the common beam path, impinges on the processing unit ( ).
