ABSTRACT:
A device for inspecting the geometry of a vehicle, in which the appearance of an element fixed to a wheel rim of the vehicle is caused to vary as a function of the angle of view at which it is seen, without thereby producing a perspective image of this element. The variation of appearance is caused by moire gratings. The device is useful for the geometric inspection of wheeled vehicles.
