  2. Optical cross section - Wikipedia

    en.wikipedia.org/wiki/Optical_cross_section

    Optical cross section (OCS) is a value which describes the maximum amount of optical flux reflected back to the source. [1] The standard unit of measurement is m 2 /sr. OCS is dependent on the geometry and the reflectivity at a particular wavelength of an object.

  3. 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 ...

    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/Laser_diffraction_analysis

    Laser diffraction analyzer. Laser diffraction analysis, also known as laser diffraction spectroscopy, is a technology that utilizes diffraction patterns of a laser beam passed through any object ranging from nanometers to millimeters in size [1] to quickly measure geometrical dimensions of a particle.

    Without a continual flow of labeled data, bottlenecks can occur and the algorithm will slowly get worse and add risk to the system. It's why labeled data is so critical for companies like Zoox ...

  8. Atmospheric lidar - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_lidar

    The concept of using lidar to detect PBL height relies on the assumption that there is a strong gradient in the concentration of aerosols in the ML versus the free atmosphere. An advantage of using remote sensing instruments over radiosondes for detection of the PBL height is the possibility of nearly continuous monitoring versus typical ...
