    Abstract: In order to reduce the exposure of a detector surface 180 of a photo-multiplier 160 to stray charged particles, an off-axis structure is interposed between the resonant structure and the detector surface of the photo-multiplier. By providing the off-axis structure with at least one reflective surface, photons are reflected toward the detector surface of the photo-multiplier while at the same time absorbing stray charged particles. Stray particles may be absorbed by the reflective surface or by any other part of the off-axis structure. The off-axis structure may additionally be provided with an electrical bias and/or an absorbing coating for absorbing stray charged particles.

    Abstract: A machine and methods measure a characteristic of an optical signal incident upon a detector characterized by one or more dynamic response parameters. One method receives an output signal from the detector and compares that output signal and a computationally determined response of the detector to a known optical signal incident upon the detector. The response is based on said one or more dynamic parameters. The method determines the characteristic based on a relationship between the output signal and the computationally determined response. Another method observes an output signal from an optical detector detecting one or more optical signals, accesses a characteristic curve of detector response, compares the observed output signal to the characteristic curve, and calculates at least one characteristic of one or more optical signals based on a relationship of the observed output signal and the characteristic curve.

    Abstract: The invention relates to an arrangement with a panel of a flat display and with a graphics processor to which a digitized image signal can be supplied by an A/D converter, said image signal being generated from an analog image signal by the A/D converter. An amplification of the A/D converter can be set in such a manner that the A/D converter generates a maximum video step of the digital image signal from the highest video level of the analog image signal. Appropriate measures are used to reduce interfering influences upon the contrast of an image due to aging effects of the transparent portions of the panel, e.g. due to aging effects of the panel glass, the LCD liquid or of the diffuser films and/or polarization films, and permit the sensor to be seen via the display surface only during a calibrating phase. The contrast is automatically adjusted on site, e.g. when the flat display is used in the medical field, thereby eliminating the need for service personnel.

    Abstract: A semiconductor light source with optical feedback includes a vertical member extending upward from an upper horizontal surface of a header parallel to a vertical beam projected from a semiconductor light-emitting element mounted on the horizontal surface of the header wherein the vertical member supports a light-sensing element for receiving light reflected transversely from the vertical beam by a beam splitter supported by the vertical member. The vertical beam passing through the beam splitter passes through a window or filter in a cap mounted on the header and covering the light-emitting element, the light-sensing element, the beam splitter, and the vertical member. Substantially all of the transversely reflected light impinges on the light-sensing element and can be used to control the power to the light-emitting element. A simple lens can by used to collimate the beam. Interior portions of the unit are formed from light absorbing materials such as black ceramic, black plastic, anodized aluminum, etc. The combined effect of the non-reflective interior of the assembly, the orientation of the photo-diode to have an acceptance cone perpendicular to the beam axis, the small entrance pupil, and the optical filter reduces ambient radiation in the unit by as much as −75 dB of the level outside the device. This reduces noise and drift in the automatic power control loop to produce constant intensity in the output light beam.
