The present invention relates to an apparatus (8) for detecting a target position deviation of two bodies (10, 12). The apparatus (8) for detecting a target position deviation of two bodies (10, 12) comprises a first measuring unit (14) for placement on the first body (10), a second measuring unit (18) for placement on the second body (12), and an evaluation unit (22). The first measuring unit (14) has a means (24) to generate at least one bundle of light beams (28) and a scattering area (34) to scatter light (WV, PV) striking the scattering area. The second measuring unit (18) has a reflection device (38) to reflect the bundle of light beams (28) onto the scattering area (34). The second measuring unit (18) has a camera (36) to record an image of the scattering area (34). The evaluation unit (22) detects a target position deviation of the bodies (10, 12) from the image. The present invention also relates to a method to detect the deviation target position. |
