| 20080274437 | METHOD AND APPARATUS FOR IDENTIFYING TOOTH-COLOURED TOOTH FILLING RESIDUES - A tooth is irradiated with light ( | 11-06-2008 |
| 20100097618 | Microscopy system, microscopy method, and a method of treating an aneurysm - A microscopy system and method allow observing a fluorescent substance accumulated in a tissue. The tissue can be observed at a same time both with visible light and with fluorescent light. It is possible to observe a series of previously recorded fluorescent light images in superposition with the visible light images. An end of the series of images may be automatically determined. A thermal protective filter may be inserted into a beam path of an illuminating system at such automatically determined end of the series. Further, the fluorescent light image may be analyzed for identifying a coherent fluorescent portion thereof. A representation of a periphery line of the coherent portion may be generated, and depths profile data may be obtained only from the coherent portion. An illuminating light beam for exciting the fluorescence may be modulated for improving a contrast of fluorescent images. | 04-22-2010 |
| 20100238541 | STEREO-EXAMINATION SYSTEMS WITH IMAGE ROTATION - A stereo-examination system including an objective arrangement configured to receive an object-side beam bundle emanating from the object plane and to convert the object-side beam bundle into an image-side beam bundle and a selection arrangement configured to select at least one pair of partial beam bundles from the image side beam bundle. The system also includes an image transmission apparatus configured to generate stereoscopic images of an object positionable in the object plane from the at least one pair of partial beam bundles and an illumination arrangement. The illumination arrangement includes a light source, a beam coupler to superpose a beam cross-section of the illumination beam with the image-side beam bundle, and a field of a plurality of state-changing elements. The elements are selectively switchable between a first state directed and a second state in which light of the illumination beam is and is not directed to the object plane. | 09-23-2010 |
