20150027196 | METHOD FOR CORRECTING MEASURED VALUES OF A SENSOR ELEMENT - A measured value of a sensor element is obtained during repeatedly executed measuring periods for performing different measurements and for setting different operating states, the sensor element being electrically connected in a periodically alternating manner, in consecutive switching positions, in a predefined order, where at least one measurement for determining the measured value is performed repeatedly within a measuring period for determining individual values at predefined switching positions, the measured value being determined from the individual values. Using the switching position within the measuring period, the operating state of the sensor element preceding the individual measurement, and therefore, the influence of the preceding circuit configuration on the individual measured value, is known, and the individual values are correspondingly corrected. By correcting the individual values, the measured value determined from the individual values is also corrected. | 01-29-2015 |

20110224658 | OPHTHALMOLOGIC LASER SYSTEM AND OPERATING METHOD - An ophthalmologic laser system and an operating method. The laser system includes a laser, a scanner unit, a focusing lens and a beam splitter that directs radiation that reaches the beam splitter from the direction of the area of examination through a confocal aperture orifice onto a detector. The invention also includes a control unit with which a cornea arranged in the examination area can be irradiated by the laser at illumination laser power and detection light can be registered by the detector. The cornea is scanned in three dimensions, in that the cornea is irradiated at multiple points and detection light is registered from there. Based on the detection light, a laser cut in the cornea is identified and the form and/or position of the laser cut calculated. The invention further relates to refractive laser surgery. | 09-15-2011 |
20110264081 | OPHTHALMOLOGICAL LASER SYSTEM AND OPERATING METHOD - A polarization beam splitter selectively decouples detection light onto a detector such that it has a polarization direction that differs from the emitted illumination light. This enables the detection of the light scattered back in the eye lens at a high level of accuracy, since stray light from reflections at optical components of the light path is suppressed. In the generating of photo disruptions or other incisions, the ray exposure of the retina may be reduced in that the incisions being furthest away from the laser are induced first such that laminar gas inclusions with an existence duration time of at least 5 seconds result. In this manner the laser radiation propagated in the direction of the retina in further incisions are scattered and partially reflected such that the influence impinging upon the retina is reduced. | 10-27-2011 |
