  • Wavelength-controlled semiconductor laser device
    Patent number: 8345719
    Abstract: A semiconductor laser device comprising a laser diode with an integrated photodiode, wherein one of the components of the laser diode with the integrated photodiode is also used for heating the laser diode. A simpler design of a wavelength-controlled semiconductor laser is thus obtained.
    Type: Grant
    Filed: September 16, 2009
    Date of Patent: January 1, 2013
    Assignee: Koninklijke Philips Electronics N.V.
    Inventors: Holger M. Moench, Philipp Gerlach, Mark Carpaij, Alexander M. Van Der Lee

  • LASER SENSOR SYSTEM BASED ON SELF-MIXING INTERFERENCE
    Publication number: 20110007299
    Abstract: A sensor module (1) for measuring the distance to a target and/or the velocity of the target (50), the sensor module (1) comprising at least one laser source (100), at least one detector (200) being adapted to detect modulated laser light and at least one control element the control element (400) being adapted to vary the focus point of the laser light and/or the intensity of the laser light and/or the direction of the laser light. The control of the laser light emitted by the laser source (100) either by active optical devices as variable focus lenses or controllable attenuators or passive optical elements in combination with arrays of laser sources (100) and detectors (200) enable flexible and robust sensor modules.
