ABSTRACT:
A laser-optical surveying system comprising a leveling system which uses a surveyor's rod wherein a laser beam rotates in a horizontal plane and is adapted to strike a surveyor's rod. The surveyor's rod is equipped with a coding representing the length, that is, in the case of a leveling system, representing the altitude, which can be read with the laser light so that an optical signal representing the altitude is generated when the laser beam passes the rod. The latter is then converted to an electronic signal and serves, when electronically processed, for displaying the height of the laser beam on the surveyor's rod.
