Abstract
The invention is directed to an optical clinometer comprising a housing or vessel with a transparent liquid which forms a liquid horizon and which is suitable for changing the direction of at least one optical beam bundle depending on inclination. At least one light source is provided for illuminating at least one structure or for generating at least one light point or light spot. An optical device is responsible for imaging the at least one structure or the at least one light point or light spot through the liquid and by of total reflection at the surface of the liquid on photoelectric sensor elements of at least one line-shaped or surface-shaped sensor arrangement, wherein the optical device for imaging the structure or the light point or light spot is arranged on the underside of the bottom of the housing or are a component part of this bottom, and the optical device is formed of an individual optical element which couples light in and out and images the structure or the light point or light spot.
