  2. Underwater vision - Wikipedia

    en.wikipedia.org/wiki/Underwater_vision

    Underwater vision is the ability to see objects underwater, and this is significantly affected by several factors. Underwater, objects are less visible because of lower levels of natural illumination caused by rapid attenuation of light with distance passed through the water.

  3. Aquascope - Wikipedia

    en.wikipedia.org/wiki/Aquascope

    An aquascope (also called bathyscope) is an underwater viewing device. It is used to view the underwater world often from dry land or a boat. It eliminates the water surface glare and allows viewing as far as water clarity and light permit. The underwater viewer can be used for observing reefs, checking boat moorings, secchi disks and other ...

    en.wikipedia.org/wiki/Perspective_distortion

    Consider an idealised Gaussian optical system, with the image and the object in the same medium.Thus, for an object in focus, the distance between the lens and image plane , the distance between lens and the object , and the focal length are related by the thin-lens equation:

  8. Ocean optics - Wikipedia

    en.wikipedia.org/wiki/Ocean_optics

    Particle size effects how much scattering happens at different colors; for example, very small particles scatter light exponentially more in the blue colors than other colors, which is why the ocean and the sky are generally blue (called Rayleigh scattering). Without scattering, light would not “go” anywhere (outside of a direct beam from ...
