  2. 3D scanning - Wikipedia

    en.wikipedia.org/wiki/3D_scanning

    There are a variety of technologies for digitally acquiring the shape of a 3D object. The techniques work with most or all sensor types including optical, acoustic, laser scanning, [13] radar, thermal, [14] and seismic. [15] [16] 3D-scan technologies can be split in 2 categories: contact and non-contact. Non-contact solutions can be further ...

  3. Hyperspectral imaging - Wikipedia

    en.wikipedia.org/wiki/Hyperspectral_imaging

    Acquisition techniques for hyperspectral imaging, visualized as sections of the hyperspectral datacube with its two spatial dimensions (x, y) and one spectral dimension (λ). In spatial scanning, each two-dimensional (2D) sensor output represents a full slit spectrum (x, λ). Hyperspectral imaging (HSI) devices for spatial scanning obtain slit ...

  9. Tomography - Wikipedia

    en.wikipedia.org/wiki/Tomography

    Volume rendering is a set of techniques used to display a 2D projection of a 3D discretely sampled data set, typically a 3D scalar field. A typical 3D data set is a group of 2D slice images acquired, for example, by a CT, MRI, or MicroCT scanner.
