The surveying system (50) has pivoting structure (20a) provided on base (20b). A motorized rotatable beam deflector (11) is provided for deflecting scanning beam (60). A second angular position surveying unit (13) is provided for determining rotation angle...

An attachment device (46) for attaching and removing a distance measuring instrument (3) to and from an angle measuring instrument comprises a base unit (61) to which the distance measuring instrument is fixed, a fixing unit (55) for fixing the base unit t...

Measuring components (7) for aligning an optical beam path with a target are mounted on a rotatable alignment component (5), and can be tilted w.r.t. the alignment component. The optical beam path can be modified by at least one piezoelectric micromotor (1...

A surveying instrument, comprising a distance measuring unit (27) for measuring a distance to a collimating point, an angle measuring unit (37, 38) for measuring a vertical angle and a horizontal angle of the collimating point, an image pick-up means (33) ...

A surveying instrument assumes either a high-speed drive control mode for driving a surveying optical system at high speed or a low-speed drive control mode for driving the surveying optical system at low speed. A motor is continuously driven through a PWM...

The invention relates to a method for measuring a distance-related variable such as distance, speed or acceleration, or for leveling. An emitting device (1-6) comprising at least one microlaser (3) is used as an emitter, and the beam reflected off an objec...
