Abstract: A method for operating a LIDAR system with at least one spectrally tunable light source emitting a light beam having a temporally varying frequency and a transparent protective shield, arranged in a light path of the light beam, protecting the LIDAR system against environmental pollution includes determining distance values of an object based on beat frequencies of beat signals resulting from a superposition of partial signals obtained from partial reflection of the light beam at the object with reference signals not reflected at the object. Each distance value is determined from a peak in a signal spectrum obtained on the basis of a Fourier transformation of the beat signal. A degree of soiling of the protective shield is diagnosed by analyzing the signal spectrum in a predefined analysis frequency range. An upper limit frequency bounding said analysis frequency range is based on a distance of the protective shield.

Abstract: A system for short pulse laser eye surgery and a short pulse laser system, in which a beam guidance device passes through a corresponding articulated arm, and through an applicator head and a microscope head of the system, which is movable in a three-dimensional volume both independently of one another as well as connected to each other. The system also includes an easy to use patient interface with a one-piece contact element, a computer program product for methods of the incision guidance and sequentially operating referencing methods with patient interfaces containing markings.

Abstract: A liquid-patient interface for fixing the relative geometric position and orientation of a patient's eye with respect to a laser applicator of an ophthalmological laser therapy system. The liquid-patient interface includes a lens element and a cone element, wherein the lens element is inserted into the cone element and permanently connected to the cone element such that the liquid-patient interface has an integral configuration. The invention furthermore relates to a corresponding production method for such a liquid-patient interface. The liquid-patient interface, the lens element of which is embodied in one piece and contains an optical zone, which has a lens function, and an envelope region, adjoining the optical zone, having a defined height not equal to zero and having an upper edge, wherein the upper edge of the lens element facilitates a direct connection to the laser applicator.
