摘要： A device configured to read an exposed imaging plate, comprises a light-source that generates read-out light. A deflection unit directs the read-out light in a scanning movement over the imaging plate. The deflection unit comprises a micromirror that deflects impinging read-out light towards the imaging plate. The micromirror swivels about a first swivel axis and about a different second swivel axis. The micromirror oscillates with a first frequency about the first swivel axis and simultaneously with a different second frequency about the second swivel axis. A detector unit detects fluorescent light which is emitted from the imaging plate at locations where the read-out light impinges.

摘要： A dental camera system for creating an image of an object has a dental camera, which comprises a housing and optics arranged therein together with an image sensor. The dental camera system further comprises an evaluation unit which cooperates with the image sensor to capture the object. To achieve a dental camera system whereof the dental camera performs using optics without movable or controllable optical elements, it is provided for the optics to be plenoptic optics which are designed to determine a 4D light field when capturing the object and for the evaluation unit to be designed to calculate at least one representation of the captured object from the 4D light field.

摘要： A device and method for reading an exposed imaging plate generate read-out light and utilize a deflection unit to direct the read-out light in a scanning movement over the imaging plate. The deflection unit has a micromirror to deflect impinging read-out light towards the imaging plate. The micromirror can swivel about a first swivel axis and about a second swivel axis distinct from the first. A detector unit detects fluorescent light emitted from the imaging plate at locations where the read-out light impinges. An evaluating unit evaluates signals received from the detector unit and builds up an image that is stored in the imaging plate. The evaluating unit takes into account, when evaluating the signals received from the detector unit, that points on the imaging plate are subjected to the read-out light variably often and/or for variable time lengths while the micromirror oscillates about the first and the second swivel axis.

摘要： A camera head of a dental camera for detecting caries in an interdental space has an illuminating device for illuminating a tooth adjacent to the interdental space, which includes an infrared light source. The camera head further includes optics which have an image plane and an object plane, wherein an image sensor is located in the image plane, and the object plane divides the space into two half spaces, wherein a first half space contains the optics and is located in front of the object plane, and a second half space is located behind the object plane, both as seen from the optics. The illuminating device and the optics are designed and arranged with respect to one another in such a way that the illuminating device is arranged in the first half space and infrared light exiting the illuminating device is aimed in the direction of the second half space.
