  2. Lidar - Wikipedia

    en.wikipedia.org/wiki/Lidar

    Lidar (/ ˈ l aɪ d ɑːr /, also LIDAR, LiDAR or LADAR, an acronym of "light detection and ranging" [1] or "laser imaging, detection, and ranging" [2]) is a method for determining ranges by targeting an object or a surface with a laser and measuring the time for the reflected light to return to the receiver.

    en.wikipedia.org/wiki/LIDAR_traffic_enforcement

    Lidar traffic enforcement. Lidar has a wide range of applications; one use is in traffic enforcement and in particular speed limit enforcement, has been gradually replacing radar since 2000. [1] Current devices are designed to automate the entire process of speed detection, vehicle identification, driver identification and evidentiary ...

  4. Atmospheric lidar - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_lidar

    Atmospheric lidar. Atmospheric lidar is a class of instruments that uses laser light to study atmospheric properties from the ground up to the top of the atmosphere. Such instruments have been used to study, among other, atmospheric gases, aerosols, clouds, and temperature.

  5. Optical heterodyne detection - Wikipedia

    en.wikipedia.org/wiki/Optical_heterodyne_detection

    Optical heterodyne detection is a method of extracting information encoded as modulation of the phase, frequency or both of electromagnetic radiation in the wavelength band of visible or infrared light. The light signal is compared with standard or reference light from a "local oscillator" (LO) that would have a fixed offset in frequency and ...

  6. Geological structure measurement by LiDAR - Wikipedia

    en.wikipedia.org/wiki/Geological_structure...

    Geological structure measurement by LiDAR technology is a remote sensing method applied in structural geology. It enables monitoring and characterisation of rock bodies. [1] This method's typical use is to acquire high resolution structural and deformational data for identifying geological hazards risk, such as assessing rockfall risks or ...

  7. Radar detector - Wikipedia

    en.wikipedia.org/wiki/Radar_detector

    A radar detector is an electronic device used by motorists to detect if their speed is being monitored by police or law enforcement using a radar gun. Most radar detectors are used so the driver can reduce the car's speed before being ticketed for speeding. In general sense, only emitting technologies, like doppler RADAR, or LIDAR can be detected.
