摘要： A compact folded signal transmission and image viewing pathway design and visual display technique for laser rangefinding instruments incorporates a beam splitting cube in the eyepiece optical space and advantageously provides an objective image focal length substantially twice that of the physical length of the instrument optical components. Through the use of some of the same optical elements in both the image viewing pathway as well as the laser transmission pathway, a relatively long transmission focal length is provided which saves in both physical instrument space and component cost while also allowing for the use of reasonably sized photodiodes with improved power output over that of previous designs.

摘要： A handheld, folded-path, laser rangefinder architecture and technique incorporating a single circuit board for mounting of both the laser emitting and detecting elements is disclosed. The architecture disclosed provides an efficient and low cost design for a laser rangefinder, and by eliminating the conventional provision of separate circuit boards for the laser transmitting and receiving elements, reduces the overall size of the unit and its cost of manufacture by concomitantly eliminating unnecessary interconnecting cables and the like.

摘要： A compact speed measurement system for field or onsite use in measuring speeds of vehicles and capturing images of select vehicles. The system includes a laser speed detector for determining a speed of a vehicle in a specific target area. When a speed is determined, the detector generates a speed signal. The system includes a camera generally aligned with the speed detector operable to capture and store digital still images of vehicles in memory. The camera is programmed to respond to an image capture signal to generate and transmit a digital image file including a still image of the vehicle targeted by the detector. A portable field processor is communicatively linked to the speed detector and the camera to first receive the speed signal, to process the speed signal and to transmit an image capture signal to the camera, and to receive the digital image file from the camera.

摘要： A highly precise range measurement instrument is made possible through the use of a novel and efficient precision timing circuit which makes use of the instrument's internal central processing unit crystal oscillator. A multi-point calibration function includes the determination of a "zero" value and a "cal" value through the addition of a known calibrated pulse width thereby providing the origin and scale for determining distance with the constant linear discharge of capacitor.

摘要： A sensor for determining the position of a movable object along a selected axis. The system includes a target positioned at a location aligned with the selected axis. An optical energy emitter is mounted on the movable object and has a beam dispersion greater than two degrees directed at the target. An optical energy receiver is mounted on the movable object and aligned to receive optical energy reflected by the target. The optical energy detector generates a receive signal indicating reception of the optical energy. A time of flight circuit coupled to the emitter and receiver generates a flight time signal indicating the elapsed time from emission of the optical energy to reception of reflected optical energy. A control circuit monitors the flight time signal and outputs a position signal indicating position of the movable object with respect to the target.

摘要： A pre-biasing technique for a transistor-based avalanche circuit which improves the initial rate of rise in the current applied through a laser diode or other light emitting device in a laser based distance measurement and ranging instrument and, therefore, the sharpness of the leading edge of the laser pulse produced. Since the timing of the flight time of a laser pulse to a target and back to the ranging instrument is determined with reference to the leading edge of the emitted laser pulse, the inherent precision obtainable is enhanced by the production of a sharper leading edge pulse. Through the use of the pre-biasing technique disclosed, the very rapid rise time pulse which may be achieved also allows for the substitution of a much cheaper light emitting diode in lieu of a conventional laser diode in an alternative implementation of a light pulsed-based distance measuring and ranging instrument.

摘要： A laser speed detector is described which includes a laser rangefinder which determines the time-of-flight of an infrared laser pulse to a target and a microprocessor-based microcontroller. The device is small enough to be easily hand-held, and includes a trigger and a sighting scope for a user to visually select a target and to trigger operation of the device upon the selected target. The laser rangefinder includes self-calibrating interpolation circuitry, a digital logic-operated gate for reflected laser pulses in which both the "opening" and the "closing" of the gate can be selectably set by the microcontroller, and dual collimation of the outgoing laser pulse such that a minor portion of the outgoing laser pulse is sent to means for producing a timing reference signal.

摘要： A self-aligned aiming system and technique for a laser rangefinder incorporating a retroreflector. In operation, a virtual dot perceived in the laser rangefinder viewing window is inherently aligned with a visible beam projected on the target and has zero parallax by design. Even if there is a slight offset in the visual pathway of the laser rangefinder, when the virtual dot in the viewing window is placed on a specific point on the target, the visual beam is located at that same specific point.
