ABSTRACT OF THE DISCLOSURE A device for measuring dimensions. A device for measuring one or a plurality of regions of an object to be able to determine one or a plurality of dimensions of said object, comprising a means (3, 1, 6) for directing a light beam towards said object, a means (6, 1, 9) for receiving light beams (8) which are reflected from said object, and a means (54, 57-64) for calculating the travel time of the beam to and from said object, with a means (56) causing the light beam to be modulated with a fixed frequency (f0), and a means (1, 2, 6) causing the light beam to sweep across said object at a defined angle/defined angles relative to a fixed plane of reference during the entire sweeping operation, the light (8) that is reflected by said object returning to intercepting means (9), via said light beam sweeping means (6, 1, 2).
