Abstract:
The invention relates to the devices for contactlessly measuring surface profiles and can be used for person identification in security systems. The inventive device for contactlessly controlling surface profile comprises a pulse illumination unit which is provided with a transparency and forms a transparency image on an object surface, and image recording unit and a computer. Said device also comprises a control unit which is connected to the image recording unit in the form of a TV camera with field interlacing, the pulse illumination unit and to the computer for synchronizing the illumination of the object surface by said pulse illumination unit with the TV camera field and for synchronizing the image processing by the computer with the TV interlacing. The transparency is embodied in the form of a line screen provided with an aperiodical different width band structure and a uniform transmission along each band, thereby making it possible to identify the sequence of the line screen images on the object surface.
