The distance-measurement apparatus executes a number of distance-measurement cycles.

The present invention relates to a portable, hand-held distance-measurement apparatus utilizing a laser range finder (100).

According to the invention, the device (10) comprises means which permits a measurement of distances with a given measuring uncertainty.

In a first aspect the invention is a method for measuring the nanometer distances.

A measurement instrument, i.e. a mobile body, measures distances between a current position of the mobile body and obstacles in the environment of the mobile body.

The use of a distance measuring device is allowed – unless a local rule prohibits it.

Distance-measuring devices would be permitted unless prohibited by a local rule.

Use of Distance-Measuring Devices - The use of DMDs will be allowed unless a Local Rule has been adopted prohibiting their use.

This distance-measuring arrangement automatically determines the distance between two supporting parts.

The invention relates to a method for measuring distances, based on the phase measurement of an optical measuring beam that is reflected or scattered by an object, on which the beam is sighted.
