  • Patent number: 7088433
    Abstract: A distance measuring apparatus measure the distance to a target by measuring the time required for an emitted beam of light to go to and return from the target. The light receiving section of the apparatus converts the received light into an electric signal. The clamp/inversion section of the apparatus clamps and inverts the output of the light receiving section. The comparing section of the apparatus compares the output of the light receiving section and the output of the clamp/inversion section. The determining section of the apparatus identifies the time of receiving the light on the basis of the outcome of the operation of the comparing section.

  • Patent number: 6864966
    Abstract: The invention relates to a method for measuring distances, based on the phase measurement of an optical measuring beam that is reflected or scattered by an object, on which the beam is sighted. According to said method, the measurement object is exposed to an optical measuring beam of modulated intensity emitted by a measuring device and is converted into electrical measurement signals. The signals are then compared with a reference signal that is generated from the detection and conversion of a portion of measuring light that has been guided on a known reference trajectory, in order to determine the distance between the measuring device and the measurement objet, based on the phase difference that has been determined. The emitted measuring beam is modulated in bursts and the measurement signal of the receiver is only evaluated during the active burst period. The invention also relates to devices for carrying out said method.

  • Patent number: 6856380
    Abstract: An aerial vehicle speed correlation method for two-dimensional visual reproduction of laser radar images of the present invention is capable of altering and controlling the output timing of the invention's laser radar system rated output lines based on the moving distance and the speed of an aerial vehicle. The speed error correlation method of the present invention is not limited to outputting one output line for every scanned line (N) for reducing the accumulation of geometric distortion error along the in-track direction of the scan frame. The speed correlation method of the present invention uses a set of generated fire table of equation to correct tangential error along the cross-track direction and to improve the reproduction quality of the laser radar images.

  • Patent number: 6803998
    Abstract: Embodiments of the invention provide an improved method and apparatus for sensing position and/or status of an object. For one embodiment, a method generally includes illuminating the object with an optical pulse source and supplying a first optical pulse to a photo-detector, causing a resonant circuit formed by the photo-detector and an inductor to generate a resonant signal. The method also includes supplying at least a second optical pulse to the photo-detector causing a change in the resonant signal, wherein the second optical pulse is reflected from the object, monitoring the change in the resonant signal, and determining a position of the object based on the monitored change in the resonant signal. A velocity, direction of travel and/or acceleration of the object may also be determined from successive position measurements.

  • Patent number: 6785032
    Abstract: A laser countermeasure system uses a fluence trigger along an optical path between an entrance and a detector at an output. The fluence trigger detects laser radiation and blocks the passage thereof beyond the trigger. A shutter at the front end can be operated in response to detection by the trigger. A threat analyzer also receives radiation and automatically breaks the radiation into spectral components for correlation to appropriate filters to remove the harmful coherent radiation. A tunable filter and/or a filter wheel is interposed along the optical path and is controlled by an adjustment system, illustratively servo controls. The adjustment system responds to the threat analyzer to select and interpose automatically the proper filter(s) to attenuate or block the coherent radiation. Thereafter, the fluence trigger and/or shutter operate to restore full operation along the optical path. The system and method provide look-through capability and mission continuity in the face of unknown laser threats.

  • Patent number: 6781683
    Abstract: Methods for operating a laser scanning system are disclosed. The laser scanning system can be used in construction projects to generate a field survey. An architect or engineer can use the field survey to create construction drawings. In addition, relevant points from the construction drawings can be identified at the construction site with the scanning system. Further, earth moving equipment can be controlled using the same information. The laser scanning system can also be used to determine if two parts can be mated together by scanning and comparing the parts that are to be mated. The laser scanning system can further be used to determine if an object can be moved through an opening in a structure by comparing scan points of the structure with scan points from the object. The laser scanning system can additionally be used to identifying objects within the site, to build databases that have relevant information about the objects, and to guide reproducing machines.
