Geodetic instruments and methods of operating geodetic instruments
First Claim
1. A total station comprising:
- a center unit, the center unit comprising;
a reflecting optical element mounted in the center unit and rotatable about an axis, wherein;
the reflecting optical element is rotatable relative to the central unit; and
the rotation of the reflecting optical element determines positions scanned at a surface of a target by the total station in a scanning mode;
a radiation source adapted to emit light to be output along an output light beam path from the total station via light reflection against the reflecting optical element; and
a receiver adapted to receive light entering the total station along an input light beam path; and
an electronic distance measurement (EDM) unit adapted to determine a distance to a position at the target based on a signal representative of light received at the receiver.

Abstract
Embodiments provide for a geodetic instrument comprising a scanning head, a reflecting optical element, a radiation source, a control unit and an electronic distance measurement (EDM) unit. The scanning head is rotatable about a first axis. The reflecting optical element mounted in the scanning head and rotatable about the same first axis. The radiation source is adapted to emit light to be output along a light beam path from the geodetic instrument via light reflection against the reflecting optical element. The control unit is adapted to adjust an angular displacement profile of the reflecting optical element about the first axis relative to an angular displacement profile of the scanning head such that an angular displacement of the light beam path about the first axis as a function of time presents a stair-like profile. The EDM unit is adapted to determine a distance to a target during a flat portion of the stair-like profile.
