  2. Light scattering by particles - Wikipedia

    en.wikipedia.org/wiki/Light_scattering_by_particles

    Multiple-scattering effects of light scattering by particles are treated by radiative transfer techniques (see, e.g. atmospheric radiative transfer codes). The relative size of a scattering particle is defined by its size parameter x, which is the ratio of its characteristic dimension to its wavelength:

  3. Scattering - Wikipedia

    en.wikipedia.org/wiki/Scattering

    Wine glass in LCD projectors light beam makes the beam scatter.. In physics, scattering is a wide range of physical processes where moving particles or radiation of some form, such as light or sound, are forced to deviate from a straight trajectory by localized non-uniformities (including particles and radiation) in the medium through which they pass.

  4. Spectroscopy - Wikipedia

    en.wikipedia.org/wiki/Spectroscopy

    In biochemical spectroscopy, information can be gathered about biological tissue by absorption and light scattering techniques. Light scattering spectroscopy is a type of reflectance spectroscopy that determines tissue structures by examining elastic scattering. [10] In such a case, it is the tissue that acts as a diffraction or dispersion ...

  5. Biological small-angle scattering - Wikipedia

    en.wikipedia.org/wiki/Biological_small-angle...

    Small-angle X-ray scattering and small-angle neutron scattering are the two complementary techniques known jointly as small-angle scattering (SAS). [2] SAS is an analogous method to X-ray and neutron diffraction, wide angle X-ray scattering, as well as to static light scattering. In contrast to other X-ray and neutron scattering methods, SAS ...

    In a statistical sense, elastic scattering of light by numerous particles much smaller than the wavelength of the light is a process known as Rayleigh scattering while the similar process for scattering by particles that are similar or larger in wavelength is known as Mie scattering with the Tyndall effect being a commonly observed result.

  7. Forward scatter - Wikipedia

    en.wikipedia.org/wiki/Forward_scatter

    Forward scattering is the deflection of waves by small angles so that they continue to move in close to the same direction as before the scattering. It can occur with all types of waves, for instance light , ultraviolet radiation, X-rays as well as matter waves such as electrons , neutrons and even water waves .

  8. Acousto-optics - Wikipedia

    en.wikipedia.org/wiki/Acousto-optics

    Acousto-optics is a branch of physics that studies the interactions between sound waves and light waves, especially the diffraction of laser light by ultrasound (or sound in general) through an ultrasonic grating. A diffraction image showing the acousto-optic effect.

  9. Attenuation - Wikipedia

    en.wikipedia.org/wiki/Attenuation

    Light scattering from many common surfaces can be modelled by reflectance. Light scattering depends on the wavelength of the light being scattered. Thus, limits to spatial scales of visibility arise, depending on the frequency of the incident lightwave and the physical dimension (or spatial scale) of the scattering center, which is typically in ...
