Abstract: A goniometer has a base defining a standing axis, a structure rotatable around the standing axis relative to the base, an angle encoder, and a control and processing unit. The structure has a graphic electronic information display arrangement having at least two display zones for displaying user guidance information and/or measuring information, a first of the at least two display zones being arranged in a first radial alignment relative to the standing axis on the structure. A second of the at least two display zones of the information display means is arranged in a second radial alignment relative to the standing axis on the structure, the first radial alignment and the second radial alignment enclosing an angle of at least 90°. The at least two display zones are automatically individually activated by the control and processing unit as a function of a fulfillment of a stored angular position criterion.

Abstract: An observation device includes at least one day vision channel, an information channel with a graphic electronic display for producing a display image and a combination optical system for combining the day vision channel and the information channel, so that a combined overall image forms.

Abstract: In a day/night-vision device, provision is made to view observations made via a day- or night-vision channel in a shared receiving channel or via an eyepiece unit as day image or night image by designing and arranging a deflector such that the same deflector is used to transfer radiation from the day- or night-vision channel into the shared receiving channel. In particular, it is also provided that further images, such as thermal images, can be transferred to the observer and can be overlaid by the day image or night image, in particular fused.

Abstract: In a day-night vision device according to the invention, it is intended that observations made via a day or night vision channel will be observed in a common receiving channel or via an eyepiece unit as a day or night image, by forming and arranging a deflection means in such a way that radiation from the day or night vision channel can be deflected by the same deflection means into the common receiving channel. In particular, it is also intended that further images, such as thermal images, can be guided to the observer and can be superposed, in particular fused, with the day or night image.
