Abstract: A profilometer incorporating a partial coherence interferometer directs a beam containing a band of wavelengths along object and reference arms of the interferometer into respective engagements with a test object surface and a reference object surface en route to a spectrometer for measuring a spectrum of the beam. Within the object arm, the test object surface is relatively moved through a range of positions offset from a null position at which optical path lengths of the object and reference arms are equal. Modulation frequencies of the beam spectrum are calculated at a succession of different focus spot positions across the test object surface. Changes in the modulation frequency are interpreted to distinguish between optical path length differences at which the optical path length of the object arm is longer or shorter than the optical path length of the reference arm.

Abstract: The invention deals with a light module, notably for motor vehicles, comprising a reflector with a reflecting surface , a screen arranged facing the reflector, the screen a semi-reflecting area, and a light guide extending longitudinally along the screen and the reflector. The guide comprises a diffusing output face extending transversally from the semi-reflecting area of the screen to the reflector. A portion of the rays exiting from the output face passes through the semi-transparent area, the other portion being also reflected toward the reflecting surface to form successive images with a depth effect of 3D type, without dark areas between these images.
