ABSTRACT:
A method and a device for measuring an angle required for ascertaining the coordinates of a measuring point comprise two laser beams which are rotatingly emitted from a reference point in opposite directions at the same angular velocity and, at a measuring point, time intervals for receiving the two laser beams are obtained and used for the ascertaining of the measuring point coordinates. The laser device generates two laser beams rotating in opposite angular directions at the same angular velocity. The laser beams are reflected twice in a pentaprism, a compound prism and a rectangular mirror. Errors for mounting the prisms and mirror are thus eliminated resulting in extremely small rotation irregularities. In a method and a device for measuring an angle in 3-dimensional space, laser beams in sectors and a sensor for detecting said laser beam are used; thereby, various angles required for determining coordinates in 3-dimensional space can be measured.
