Problems solved by technology

Although each ADM sends their measurement radiation via a single exit optical unit, they are in each case separate, independent units
The need to provide two completely independent, separate absolute position measuring devices is disadvantageously complex in terms of production process and therefore expensive

Embodiment Construction

[0046] figure 1 , figure 2 with image 3 An exemplary embodiment of the laser tracker 1 according to the present invention is shown. The laser tracker 1 shown includes a base 40, a support body 20 mounted on the base 40 and having a handle 21, and a beam guiding unit 10 mounted on two pillars of the support body 20. The laser tracker 1 is arranged on the support 45 and includes: a control and evaluation unit; an angle sensor for detecting the rotation angle of the beam guiding unit 10 relative to the base 40; and an optical distance measuring unit having at least one first beam source (For example, one or more laser diodes or super luminous LEDs), at least one first detection unit (for example, an electronic distance measurement unit), an absolute distance unit (ADM) or an interferometer unit (IFM) (not shown here) . With proper synchronization of the angle sensors, the two angles and at least one distance determined by the first measurement radiation 36 can be combined to fo...

Abstract

A laser tracker, method and storage medium for determining the industrial coordinate position of a target. A laser tracker (1) for industrial coordinate position determination of targets (61, 64), wherein the laser tracker (1) comprises at least: a control and evaluation unit, a base (40) and a beam guiding unit (10), A device for detecting the rotation angle of a beam guiding unit relative to a base and a first optical distance measuring unit (2) having at least a first beam source (30) and a first detecting unit (12). The distance measuring unit (2) as well as the control and evaluation unit are designed for realizing the first measuring function and the second measuring function, for which purpose at least one element of the distance measuring unit (2) is designed for the first measuring function Dual-purpose in both, and a second measurement function. The first measurement function is designed for coordinate position determination of a retroreflective target (61), and the second measurement function is designed for coordinate position determination of a diffuse scattering target (64).

Description

Technical field [0001] The invention relates to a laser tracker with an optical distance measuring unit for determining the industrial coordinate position of a target and a method for determining the coordinate position. Background technique [0002] Laser trackers are used for industrial measurement, such as, for example, for the determination of the coordinate position of points of parts such as vehicle bodies in the detection environment or continuous position monitoring of moving machine parts. This laser tracker is designed to determine the coordinate position of the target point and is usually used for continuous tracking of retroreflective target points. In this case, the target point may be represented by a retroreflective unit (for example, a cube prism) that is a target of an optical measurement beam (specifically, a laser beam) generated by the beam source of the measuring device or the beam source of the measuring device. The laser beam is reflected back to the measu...
