Abstract: An imaging system includes an imaging scope, a controller, a camera, and a processor. The imaging scope is selectively rotatable about a longitudinal axis relative to a horizon plane. The imaging scope has at least three optical channels, each including a respective objective that captures light. The objectives are positioned such that respective viewing direction axes of the optical channels extend at least substantially parallel to one another. The controller activates a pair of optical channels that is at least as parallel relative to the horizon plane as any other pair of optical channels. The camera generates a first image representative of light captured by a first optical channel of the activated pair of optical channels, and a second image representative of light captured by a second optical channel of the activated pair of optical channels. The processor generates a 3D image using the first and second images.

Abstract: An apparatus for capturing a stereo image includes a first objective for producing a first image, a second eye objective for producing a second eye image, a first viewing direction device rotatable about a first axis assigned the first objective, and a second viewing direction device rotatable about a second axis assigned the second objective. The viewing direction of the apparatus is rotatable by simultaneous rotation of the first and second viewing direction devices. The first objective or part is movable in a translational fashion. A cam mechanism is provided and embodied to couple a rotation of the first viewing direction device to a translational movement of the first objective or part.

Abstract: An optical medical instrument, in particular an endoscope or exoscope, has an elongate tubular shaft, a heat source generating lost heat, and a heat pipe which extends inside the shaft, in the longitudinal direction of the shaft, and has a distal heat pipe end and a proximal heat pipe end, wherein the heat pipe is thermally coupled to the heat source in order to collect heat from the latter and remove the heat from the heat source. Between the distal heat pipe end and the proximal heat pipe end, the heat pipe is coupled thermally conductively and two-dimensionally to the shaft over at least a partial length of the heat pipe and over at least a partial circumference of the heat pipe, in order to remove heat from the heat pipe, over at least a partial length and over at least a partial circumference of the shaft, to the environment.

Abstract: An observation device is provided with an image acquisition unit comprising at least one image sensor, an image display unit, that is arranged for displaying image data that is provided by the image acquisition unit, an image processing unit for image processing procedures, and a control unit comprising a multi-axis input module. The image acquisition unit is configured to provide recorded images having a predefined recording pixel quantity. The image display unit is configured to display images having a predefined display pixel quantity, wherein the recording pixel quantity is equal to or greater than the display pixel quantity. Image pixels of the display pixel quantity are obtained from the recording pixel quantity. Subsets of the recording pixel quantity are selected to form the display pixel quantity. Image acquisition parameters and display parameters are controlled by the input module.
