Patent number: 5103088Abstract: An optical sensor device for recognizing optical irradiation and detecting its direction is constructed as a spherical-shell section from dielectric, optically transparent material. The irradiation penetrating into the spherical-shell section is reflected back and forth between the exterior and the interior surface or between a mirror and a thin shell via an air gap or vacuum gap, and is thus deflected to the shell edge. Since signals of different intensities are received at the irradiation detector at the beam edge according to the direction of incidence, the direction of incidence of the irradiation can be determined from the relationship of the signals.Type: GrantFiled: July 5, 1990Date of Patent: April 7, 1992Assignee: Messerschmitt Bolkow Blohm GmbHInventors: Thorsteinn Halldorsson, Konrad Altmann, Ernst A.

Patent number: 5098427Abstract: A surgical laser instrument suitable for the alternate contant cutting and no-contact coagulating of biological tissue by means of a fiber-optically guided irradiation of a laser. Radiation which is emitted by the pyrolytic glowing of at least partially carbonized biological tissue, is received by the distal end of the fiber-optic light guide, guided back to a radiation detector, and is detected in a spectral region between 0.3 and 0.9 .mu.m, while the laser radiation is filtered out. The radiation output of the laser is controlled by means of the detector output signal, to a value under the destruction threshold of the fiber-optic light guide in such a manner that the radiation emitted during the burning of the biological tissue to be cut as well as of the tissue residues adhering to the distal end of the fiber-optic light guide and burnt into it, does not exceed a predetermined value.Type: GrantFiled: October 10, 1990Date of Patent: March 24, 1992Assignee: Messerschmitt-Bolkow-Blohm GmbHInventors: Stefan Hessel, Gerhard Hauptmann
