Solution

Endoscopy:
The non-ionizing imaging technology that is used to investigate the interior of the human body is called endoscopy.
Principle:
Endoscopes generate a picture of the inside of the body using optical fibers. A bundle of optical fibers could be inserted into the body by a doctor. Some convey illumination into the body, while others reflect lighting off internal body components back outward.
The endoscope employs the total internal reflection concept using optical fibers. This procedure is used to study the interior of a hollow organ or cavities throughout the body.
An endoscope is made up of an optical system that carries illumination to the item being seen and either the equivalent. This illuminating light is carried towards the object by an optical fiber package throughout most current endoscopes.
Therefore, the principle of total internal reflection is used in the endoscope by using optical fibers.
