Fiberscope

Guiding of light by refraction, the principle that makes fiber optics possible, was first demonstrated by Daniel Colladon and Jacques Babinet in Paris in the early 1840s.

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.

[1] In the 1960s the endoscope was upgraded with glass fiber, a flexible material that allowed light to transmit, even when bent.

[4] 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.

Fiberscopes can also be used in a military or police application to check beneath doors or around corners, or otherwise perform surveillance or reconnaissance.
