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 ...
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. They are also blurred by scattering of light between the object and ...
A telescope, which uses its large objective lens or primary mirror to create an image of a distant object and then allows the user to examine the image closely with a smaller eyepiece lens, thus making the object look larger. A microscope, which makes a small object appear as a much larger image at a comfortable distance for viewing. A ...
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:
A team of oceanographers led by Schmidt Ocean Institute have discovered and mapped a new seamount on the Nazca Ridge 900 miles off the coast of Chile.
While ocean color is a key theme of ocean optics, optics is a broader term that also includes the development of underwater sensors using optical methods to study much more than just color, including ocean chemistry, particle size, imaging of microscopic plants and animals, and more.
Molly Shannon. Molly Shannon’s comedy was all-in, all the time. During her six-season run, she threw herself—literally—into every performance, crafting characters that were as chaotic as ...
If you're doing a full eye makeup look, Allan says you can never go wrong with a smoky eye, and can even use it to make your eyes look bigger. "The key is to work with your eye shape," he says.
