  • Reflector for electrooptical distance measurement
    Patent number: 4352556
    Abstract: A reflector for electrooptical measurement of the distance between a first (3) and a second point (4) is arranged with a right angle sighting device (13) in a common case (8). The reflector (6) may thus be set up at a point (5) where the directions to the first (3) and second points (4) form a right angle. This facilitates the distance measurement between points (3, 4) that are not suited for the set up of reflectors or where visual contact between the points (3, 4) is impaired by an obstacle (1).
