  • Patent number: 9519052
    Abstract: An optical device is disclosed that may be employed in distance measuring devices. In at least one embodiment, the optical device includes a control unit that is adapted to cause at least one control signal generator unit to generate at least one control signal according to a predetermined temporal function on the basis of an elapsed time from a predetermined point in time. On the basis of the generated at least one control signal, at least one parameter of a receiver unit may be adjusted during the travel time of the optical pulse, wherein the at least one parameter affects the dynamic range of the receiver unit. In this way, the dynamic range of the receiver unit may be increased. A method is further disclosed for operating such an optical device, along with a distance measuring device including such an optical device and a surveying instrument including such a distance measuring device.

  • Patent number: 9160140
    Abstract: It is disclosed a method for driving a laser diode such as to enable mitigation or elimination of so called spiking effects related to the number of injected carriers in the laser overshooting the equilibrium value at the beginning of the lasing process. In this manner, among other things, the efficiency of a master oscillator power amplifier that may be utilized in range finding applications will be improved. It is further disclosed an optical pulse transmitter comprising such a laser diode.

  • Patent number: 9157989
    Abstract: Methods and apparatus are presented for distance measurement using laser pulses in which at least one of an attenuation function and an offset of the attenuation function relative to the send pulse is variable to accommodate differing measurement needs. In some embodiments, at least one of an attenuation function and an offset of the attenuation function is fixed relative to the send pulse for some number of measurement cycles and information derived from the result is used to modify either or both of the attenuation function and offset of the attenuation function relative to the send pulse for subsequent measurement.
