    en.wikipedia.org/wiki/Time-of-flight_detector

    A time-of-flight (TOF) detector is a particle detector which can discriminate between a lighter and a heavier elementary particle of same momentum using their time of flight between two scintillators [1]. The first of the scintillators activates a clock upon being hit while the other stops the clock upon being hit.

  3. Time-of-flight camera - Wikipedia

    en.wikipedia.org/wiki/Time-of-flight_camera

    Time of flight of a light pulse reflecting off a target. A time-of-flight camera (ToF camera), also known as time-of-flight sensor (ToF sensor), is a range imaging camera system for measuring distances between the camera and the subject for each point of the image based on time-of-flight, the round trip time of an artificial light signal, as provided by a laser or an LED.

    Time-of-flight (TOF) PET: For modern systems with a higher time resolution (roughly 3 nanoseconds) a technique called "time-of-flight" is used to improve the overall performance. Time-of-flight PET makes use of very fast gamma-ray detectors and data processing system which can more precisely decide the difference in time between the detection ...

  5. Time of flight - Wikipedia

    en.wikipedia.org/wiki/Time_of_flight

    Basic time-of-flight principles applied to laser range-finding. Time of flight (ToF) is the measurement of the time taken by an object, particle or wave (be it acoustic, electromagnetic, etc.) to travel a distance through a medium. This information can then be used to measure velocity or path length, or as a way to learn about the particle or ...

  8. Laser rangefinder - Wikipedia

    en.wikipedia.org/wiki/Laser_rangefinder

    Time of flight - this measures the time taken for a light pulse to travel to the target and back. With the speed of light known, and an accurate measurement of the time taken, the distance can be calculated. Many pulses are fired sequentially and the average response is most commonly used.

  9. Lightning detector - Wikipedia

    en.wikipedia.org/wiki/Lightning_detector

    Ground-based systems that use multiple locations and time-of-flight detection methods must have a central device to collect strike and timing data to calculate location. In addition, each detection station must have a precision timing source that is used in the calculation.
