77:, 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.
133:. The opposite applies if the light is traveling from a dense medium to a less dense medium. In optic cables, light travels through the dense glass core (high refractive index) by constantly reflecting from the less dense cladding (lower refractive index). This happens because the surface of the core acts like a perfect mirror and the angle of the light is always larger than the critical angle.

Fiberscopes are used in the medical field as a tool to help doctors and surgeons examine problems in a patient’s body without having to make large incisions. This procedure is called an endoscopy. Doctors use this when they suspect that a patient’s organ is infected, damaged, or cancerous. There are

Fiberscopes work by utilizing the science of fiber-optic bundles, which consist of numerous fiber-optic cables. Fiber-optic cables are made of optically pure glass and are as thin as a human’s hair. The three main components of a fiber-optic cable are:
