  2. Dazzler (weapon) - Wikipedia

    en.wikipedia.org/wiki/Dazzler_(weapon)

    The Outfit DEC or Laser Dazzle Sight (LDS) is a British ship-based laser. The veiling-glare laser utilizes ultraviolet light and is designed to dazzle by causing fluorescence in the lens of the human eye. There are other such laser weapon systems in development.

  3. Signal-to-noise ratio (imaging) - Wikipedia

    en.wikipedia.org/wiki/Signal-to-noise_ratio...

    Traditionally, SNR is defined to be the ratio of the average signal value to the standard deviation of the signal : [2] [3] = when the signal is an optical intensity, or as the square of this value if the signal and noise are viewed as amplitudes (field quantities).

  4. LiDAR explained: What this laser tech can do for your new iPhone

    Rumor has it that LiDAR integration is just one of the things we can expect from the theoretical iPhone 12 when it comes out later this year. Naturally, Apple's probably got all kinds of weird new ...

  5. Laser pointer - Wikipedia

    en.wikipedia.org/wiki/Laser_pointer

    Red (635 nm), blueish violet (445 nm), and green (520 nm) laser pointers. A laser pointer or laser pen is a (typically battery-powered) handheld device that uses a laser diode to emit a narrow low-power visible laser beam (i.e. coherent light) to highlight something of interest with a small bright colored spot.

  6. LaserActive - Wikipedia

    en.wikipedia.org/wiki/LaserActive

    The LaserActive 3-D Goggles (model GOL-1) employ an active shutter 3D system compatible with at least six 3D-ready LD-ROM software titles: 3-D Museum (1994), Vajra 2 (1994), Virtual Cameraman 2 (1994), Dr. Paolo No Totteoki Video (1994), Goku (1995), and 3D Virtual Australia (1996), the last software title published for the LaserActive.

  7. 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.

  8. Streak camera - Wikipedia

    en.wikipedia.org/wiki/Streak_camera

    A streak camera is an instrument for measuring the variation in a pulse of light's intensity with time. They are used to measure the pulse duration of some ultrafast laser systems and for applications such as time-resolved spectroscopy and LIDAR .

  9. Lasers and aviation safety - Wikipedia

    en.wikipedia.org/wiki/Lasers_and_aviation_safety

    To give another example, of a more powerful laser—the type that might be used in an outdoor laser show: a 6-watt green (532 nm) laser with a 1.1 milliradian beam divergence is an eye hazard to about 1,600 feet (490 meters), can cause flash blindness to about 8,200 feet (1.5 mi/2.5 km), causes veiling glare to about 36,800 feet (7 mi; 11 km ...
