摘要： An optical system comprising an optical coherence tomography (OCT) measuring device and a beam deflection unit for laterally deflecting the position or angle of a beam path of the OCT measuring device.
There is an optical component in the beam path, said optical component being embodied in such a way that a back-reflection of the optical component has a different configuration in terms of its longitudinal location along the beam path depending on the lateral position of the deflected beam path on the optical component.
The optical system comprises an evaluation unit which is embodied in such a way that a value of the lateral position or angle deflection of the beam deflection unit is determinable on the basis of a longitudinal location of the back-reflection at the optical component determined by the OCT measuring device.-

摘要： A reflector arrangement for determining the position or marking of target points, having at least one retroreflector, and a beam detection unit, by means of which the orientation measurement radiation passing through the retroreflector is acquirable. The beam detection unit comprises a first sensor for generating a signal in dependence on an acquisition of orientation measurement radiation and a first beam guiding unit. The first sensor and the first beam guiding unit are arranged such that a detection field of view for acquiring the orientation measurement radiation is defined, an alignment of the detection field of view around the yaw axis is variable and orientation measurement radiation passing through the retroreflector is acquirable in dependence on the alignment of the detection field of view with the first sensor.

摘要： A capture device for imaging a person, in particular the face or a part of the face of the person, the capture device comprises at least one camera for capturing an image of the person. The capture device comprises an infinity mirror comprising at least two mirror surfaces arranged oppositely from each other, a light source for emitting light, and a front side to look inside the infinity mirror. The infinity mirror is arranged at the capture device and placed and oriented relative to the capture device so that a capture range with an insight axis and an insight distance for the person is defined and defined capturing of the person by means of the at least one camera is provided when the person is positioned according to the capture range.

摘要： A system for monitored additive manufacturing of an object, comprising a manufacturing unit], designed for additive manufacturing of the object based on metal-containing manufacturing material in a manufacturing volume, wherein the object is built up by repeated layer-by-layer provision of the manufacturing material in defined quantity and accurately-positioned forming of the provided manufacturing material. The system moreover comprises an optical checking unit having at least one projector and two cameras and a control and processing unit. The manufacturing volume comprises an optical transmission region, the projector and cameras—are arranged outside the manufacturing volume in a fixed position relationship and are aligned in such a way that respective optical axes extend through a respective transmission region, by means of the projector, a projection can be generated on a manufacturing area and at least a common part of the manufacturing area on which the projection can be overlaid can be captured.

摘要： A reflector arrangement for position determination and/or marking of target points, comprising a retroreflector and a first sensor arrangement, by means of which the orientation measurement radiation passing through the retroreflector is acquirable. The first sensor arrangement comprises a first optical assembly providing a fisheye lens, and a first sensor, wherein the retroreflector and the first sensor arrangement are arranged in such a way that orientation measurement radiation passing through the retroreflector is projectable onto the detection surface of the first sensor by means of the first optical assembly.
