  • Method and arrangement for measuring distance
    Patent number: 5673111
    Abstract: Method and arrangement for measuring distance, in which an area (5) on a measured object (2) is illuminated with light from a laser-light source (3). After reflection, the light reproduces the illuminated area on a detector arrangement (7), placed at the side of a line through the light source (3) and the illuminated area. The detector arrangement (7) consists of a number of detector elements (14). With the aid of a scanning device the image of the area (5) is scanned with respect to light intensity and the light intensity-dependent output signals from each of the detector elements obtained during scanning is accumulated in an evaluation device.
