  • Patent number: 5353228
    Abstract: A method for target-range measurement of round-trip transit time, for laser light pulses transmitted from the rangefinder and target-reflected back to a measuring device, is based on the fact that a predetermined measurement cycle is subdivided into time intervals and that, in each time interval, it is recorded whether a reflected light pulse has or has not arrived. A system for carrying out the method is characterized by the fact that, instead of totalizing counter modules, successive storage locations in a serial memory device are sequentially indexed under clock-pulse control and, depending upon the time at which a target-reflected pulse is detected, a logic signal is supplied for storage at the instantaneously receptive location within the memory device. Signal-evaluation apparatus including a microprocessor is connected to the memory device to evaluate range from the memory location at which the logic signal is found.

  • Patent number: 5144356
    Abstract: In order to eliminate the influence of temperature on the focus of an IR optical imaging system, radiation from an auxiliary heat source is deflected through the IR optical imaging system such that said radiation impinges on an autocollimating reflector from where it is reflected back into said IR optical imaging system and then impinges on detector elements which are arranged in a detector image plane. Electrical signals generated by the affected detectors are analyzed, digitized, and then compared in a computer whose output signals control a motor for adjusting the axial position of at least one of the optical lens elements of the IR system such that the autocollimating condition between the auxiliary heat source and its image in the detector plane is maintained at all times.
