  • Patent number: 7262863
    Abstract: A distance measuring device has at least one oscillator (26) which produces a basic signal at a fundamental frequency (f0) and a first circuit device (30) which produces a first signal at a first frequency (f1) which is higher than the fundamental frequency (f0). The first circuit device (30) has at least one PLL circuit (32) and one VCO circuit (34).

  • Patent number: 7075626
    Abstract: The invention is based on a laser range finder that has a transmitter unit (10) with at least one laser, a receiver unit (12), and a single sideband modulation unit (14) that can use a first single sideband modulation frequency (ZF1) generated by an oscillator unit (16) and a carrier frequency (T1) to generate a modulation frequency (S1) of the transmitter unit (10). According to the invention, the oscillator unit (16) can generate at least one additional frequency (ZF2) and the single sideband modulation unit (14) can use the additional frequency (ZF2) to generate a demodulation frequency (S2) of the receiver unit (12).

  • Patent number: 6833909
    Abstract: The invention relates to a device for optical distance measurement, having a emitter unit (12) having a light source (17, 18) emitting modulated optical beam (13, 20, 22) to a target object (15), and having a receiver unit (14), spaced apart from the optical axis (38) of the emitter unit (12) with at least one optical detector (54) for receiving the optical beam (16, 49, 50) returning from the target object (15), and having a control and evaluation unit (36) for ascertaining the distance (48) of the device from the target object (15). It is proposed that the active, light-sensitive face (66, 67, 68, 69) of the detector (54) of the receiver unit (14) narrows in the direction (61) of a beam displacement for decreasing target object distances (48) that is due to the parallax of the returning beam (16).

  • Patent number: 6324888
    Abstract: An auxiliary housing for holding a distance measuring device has a housing part which forms a receptacle for insertion of the distance measuring device, a threaded bushing for mounting the housing part on a tripod, the threaded bushing having a longitudinal axis which coincides with an abutment surface operating as a reference surface for a hand-guided measuring process when the distance measuring device is inserted in the housing part.
