What is a stereoscope?
Stereoscope is a browsing device that allows users to create a three -dimensional image from a set of two -dimensional photos or drawings. The original stereoscopes were popular at the turn of the 20th century and contained a clip for holding special stereoscopic cards on site. The viewer would look at the basic binocular system that forced each eye to see only one of two paintings. Either by crossing or deviating the eyes would eventually appear a third picture in the middle, and this picture would give the illusion of depth until the viewer maintains the correct concentration and focus.
The secret behind the stereoscope was a relative perspective of photographs or drawings. When both eyes are trained in the same two -dimensional image, the viewer's brain does not get enough divergent information to create a binocular or three -dimensional image. The photo remains two -dimensional, without depth. However, if two pictures are taken at the same distance apart as the eye of the viewer, the brain can merge images into one sterean eKopic mental image. The stereoscope helps to achieve this visual trick.
Looking through a stereoscope, each eye sees only one of the two pictures on the stereoscope tab. In order to create a perceived three -dimensional image, the viewer either intersects or deviates them out. Each picture, left and right, should meet together and create a third picture. Since both photographs were deployed about the length of the eye, the brain now has enough information to create a sense of depth in this new image. Some people can intuitively view a stereographic card and achieve the same results without a stereographer, but the device helps viewers concentrate each eye on a separate picture.
The concept of the stereographer was further refined during the beginning to the middle of the 20th century, including the distribution of special stereoscopic cameras that amateur photographers could use to create their own stereosOpice cards. These cameras used two separate lenses and film supplies that moved apart about two and a half inches to capture stereoscopic views of popular natural places and tourist destinations. Stereoscopes and stereoscopic cards can often be purchased at gifts near popular websites.
Perhaps the best-known example of a modern stereoscope is a children's toy known as View-Master®. View-Master® is equipped with a binocular personal viewer that can accommodate special stereoscopic discs. These pictures appear in separate lenses of the viewer and the user sees a three -dimensional image without having to cross or deviate his eyes unnaturally. It is a huge improvement compared to visual gymnastics, which often requires the original stereoscope system.
While the original stereoscope might have fallen out of kindness, the idea of crumb -dimensional images from two -dimensional sources. Recently a new form of artificial stereoscopic images called autostereogram or “MagickThe eye "completely eliminated the need for a special browser. The original two -dimensional image, which often appears to be a random set of dots and lines, contains enough stereoscopic information for the viewer to create a three -dimensional image.
