What is a fiber optic camera?
A fiber optic camera, or fiberscope, is a bundle of optical fibers which transmits an image from one end, typically from a lens, to the other, where an eyepiece or camera is affixed. This can be used to view inside the human body, machinery, sewer infrastructure, and other places that are generally difficult to access in order to diagnose internal problems. These are also known as endoscopes in medical contexts, or borescopes (sometimes “boroscopes”) otherwise.

These cameras are almost always made using special imaging fiber, which consists of hundreds to thousands of small cores packed into a jacket no larger than a typical single-core fiber. Each of these cores is responsible for carrying the light of a single pixel in the transmitted image. An additional ring of optical fibers around the image transmission fibers (or rod lens, in the case of a rigid borescope) may also be used to transmit light to the object.
