An aircraft (1) or spacecraft photogrammetric procedure has an optical detector with distance measurements to support points (5) on the surface (2) that are associated with a larger number of image points (3a) and used to provide constraints on the topogra...

Method for evaluation of data that is not directly processable and which is communicated between two geodetic units (8, 9, 9') involves use of reference lists (10) and data lists. These are optimally transmitted in conjunction with the data and indicate pr...

Electronic display and control device for a geodesic measurement instrument has an electronic display device for presentation of a measurement area that is separate from the recording means and input and control devices for input of data for controlling th...

Electronic radiation is emitted (1,2,3,4) at at least two carrier wavelengths, and received (7,8,9). A first semiconductor laser (2) emits a first carrier wavelength in the infrared or red wavelength range. A second semiconductor laser (3) emits a second c...

The time of flight of two different carrier wavelengths along a measurement path is measured, with one wavelength in the wavelength range in which there is no molecular or atomic absorption and the other in a range with molecular or atomic absorption and e...

In an optical measuring system for e.g. determining spatial position and orientation of objects a plurality of measuring points on the object is registered by cameras, laser measuring devices or a combination thereof. For identifying the measuring points, ...

The invention relates to a method for measuring a distance-related variable such as distance, speed or acceleration, or for leveling. An emitting device (1-6) comprising at least one microlaser (3) is used as an emitter, and the beam reflected off an objec...

Light emitter comprises a number of partial light sources (3a-3d) that generate partial beams (5a-5d) that are collected by collecting optics (2) and guided to the aperture of a collimator (1). The collecting optics (2) has two half-reflecting plates (12a,...

In order to improve target illumination, a light source (2) of an emitter, which has a laser diode (3) configured as an edge emitter with a wavelength of 1'550 nm, has beam forming optics (4) mounted downstream in relation thereto, which comprise a cylindr...
