fiberscope
A fiberscope is a flexible fiber-optic bundle with an eyepiece on one end and a lens on the other that is used to examine and inspect small, difficult-to-reach places such as the insides of machines, locks, and the human body.
== History ==
The concept of fiber optics began in 1854 when John Tyndall discovered that light could be conducted through a curved stream of water, proving that light could be bent. Then in 1930, Heinrich Lamm, a German medical student, became the first person to put together a bundle of optical fibers to carry an image. These discoveries led to the invention of endoscopes and fiberscopes.〔(【引用サイトリンク】first1=Mary )〕
In the 1960s the endoscope was upgraded with glass fiber, a flexible material that allowed light to transmit, even when bent. While this provided users with the capability of real-time observation, it did not provide them with the ability to take photographs. In 1964 the fiberscope, the first gastro camera, was invented. It was the first time an endoscope had a camera that could take pictures. This innovation led to more careful observations, and more accurate diagnoses.〔(【引用サイトリンク】url=http://www.olympus-global.com/en/corc/history/story/endo/fiber/ )〕
