The water color spectrum as seen by a satellite sensor is defined as an apparent optical property (AOP) of the water. This means that the color of the water is influenced by the angular distribution of the light field and by the nature and quantity of the substances in the medium, in this case, water. [2]
Signal strength plays an important role in the literature of binocular rivalry and visual suppression. Similarly in BSS, it is one of the factors that determine which stimulus gets suppressed perceptually. It is a multidimensional construct that is related to the stimulus' properties.
Military binoculars of the Cold War era were sometimes fitted with passive sensors that detected active IR emissions, while modern ones usually are fitted with filters blocking laser beams used as weapons. Further, binoculars designed for military usage may include a stadiametric reticle in one eyepiece in order to facilitate range estimation. [85]
Apart from testing binocular functions, Bagolini striated glasses can measure cyclotropia.The principle of the test is similar to that of double Maddox rod test. The glasses are placed in the trial frames with the striations vertical, giving rise to two horizontal line images when viewing a spotlight.
Many anti-reflection lenses include an additional coating that repels water and grease, making them easier to keep clean. Anti-reflection coatings are particularly suited to high-index lenses, as these reflect more light without the coating than a lower-index lens (a consequence of the Fresnel equations). It is also generally easier and cheaper ...
Image-stabilized binoculars are binoculars that have a mechanism for decreasing the apparent motion of the view due to binocular movement. [1] Such binoculars are designed to minimize image shaking in hand-held applications. Higher-power binoculars magnify the image more, but the image shift is also increased. This means that even minor hand ...
The chevron test is used to determine the fracture toughness of brittle construction materials. The fracture toughness is a basic material parameter for analyzing the bond strength. The chevron test uses a special notch geometry for the specimen that is loaded with an increasing tensile force.
In order to see a clear image, the eye must focus rays of light on to the light-sensing part of the eye – the retina, which is located in the back of the eye.This focusing – called refraction – is performed mainly by the cornea and the lens, which are located at the front of the eye, the anterior segment.
