  2. Structured-light 3D scanner - Wikipedia

    en.wikipedia.org/wiki/Structured-light_3D_scanner

    Compared to 3D laser scanning, structured-light scanners can offer advantages in speed and safety by using non-coherent light sources like LEDs or projectors instead of lasers. This approach allows for relatively quick data capture over large areas and reduces potential safety concerns associated with laser use.

  3. 3D scanning - Wikipedia

    en.wikipedia.org/wiki/3D_scanning

    The advantage of structured-light 3D scanners is speed and precision. Instead of scanning one point at a time, structured light scanners scan multiple points or the entire field of view at once. Scanning an entire field of view in a fraction of a second reduces or eliminates the problem of distortion from motion.

  4. Computer stereo vision - Wikipedia

    en.wikipedia.org/wiki/Computer_stereo_vision

    The active stereo vision is a form of stereo vision which actively employs a light such as a laser or a structured light to simplify the stereo matching problem. The opposed term is passive stereo vision. Conventional structured-light vision (SLV) employs a structured light or laser, and finds projector-camera correspondences. [2] [3]

  5. Structured light - Wikipedia

    en.wikipedia.org/wiki/Structured_light

    Structured light is the process of projecting a known pattern (often grids or horizontal bars) on to a scene. The way that these deform when striking surfaces allows vision systems to calculate the depth and surface information of the objects in the scene, as used in structured light 3D scanners .

  6. Super-resolution microscopy - Wikipedia

    en.wikipedia.org/wiki/Super-resolution_microscopy

    By 1978, the first theoretical ideas had been developed to break the Abbe limit, which called for using a 4Pi microscope as a confocal laser-scanning fluorescence microscope where the light is focused from all sides to a common focus that is used to scan the object by 'point-by-point' excitation combined with 'point-by-point' detection. [14]

  7. White light scanner - Wikipedia

    en.wikipedia.org/wiki/White_light_scanner

    A white light scanner (WLS) is a device for performing surface height measurements of an object using coherence scanning interferometry with spectrally-broadband, "white light" illumination. Different configurations of scanning interferometer may be used to measure macroscopic objects with surface profiles measuring in the centimeter range, to ...
