Abstract: The invention relates to an optical inclinometer, in which radiation is emitted form a radiation source. After passing through a receptacle containing at least one first medium, said radiation is reproduced in a camera. Information concerning the inclination of the inclinometer can be gathered from the position of the first medium, in particular a liquid level, in relation to the inclinometer or the camera. The recording of the position of the first medium by a camera permits the evaluation of a plurality of characteristics, in particular the form, dimension and position of a boundary layer.

Abstract: The invention relates to a method for ensuring interaction between a distance meter and a surveying application. The system used for carrying out the inventive method comprises a computer unit (la) for executing the surveying application (2a), a distance-measuring element for measuring the distance to an object (4a) and recording a measured distance value that can be processed by the surveying application, and a remote-control element which has a wireless communication link (6a) with the computer unit (1a) for the purpose of interaction between the distance meter and the surveying application (2a).
