  2. 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.

    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.

    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.

  5. 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.

  6. 3D scanning - Wikipedia

    en.wikipedia.org/wiki/3D_scanning

    The latter method is commonly used because mirrors are much lighter and can thus be rotated much faster and with greater accuracy. Typical time-of-flight 3D laser scanners can measure the distance of 10,000~100,000 points every second. Time-of-flight devices are also available in a 2D configuration. This is referred to as a time-of-flight ...

  7. WiTrack - Wikipedia

    en.wikipedia.org/wiki/WiTrack

    A challenge would derive from multipath effects, which create errors in mapping the delay of a reflection to the distance from the target. Sometimes the transmitted signal is reflected from walls and any home appliances. A major issue that is currently being fixed is the measuring time of flight is difficult since RF signals travel

  8. Indoor positioning system - Wikipedia

    en.wikipedia.org/wiki/Indoor_positioning_system

    Time of arrival (ToA, also time of flight) is the amount of time a signal takes to propagate from transmitter to receiver. Because the signal propagation rate is constant and known (ignoring differences in mediums) the travel time of a signal can be used to directly calculate distance.

  9. Canesta - Wikipedia

    en.wikipedia.org/wiki/Canesta

    This enables time of flight ranging using a low cost CMOS process. [ 14 ] [ 19 ] Using Canesta technology a 3D time-of-flight camera can be constructed from a Canesta CMOS time of flight sensor, an imaging lens to focus the light from the scene onto the sensor and an LED or laser diode based light source controlled by the sensor to illuminate ...
