How is total internal reflection used in the construction of endoscopes

Posted on 18.06.2018 by Helene
When light is introduced into the inner core at one end, it will propagate along the fibre in a zigzag path undergoing a series of total internal reflections. The examples are animated in such a way that, not only can you connect the phenomenon with what you see, but also get an in-depth understanding in a wider area. Flexible endoscopes have a tiny camera attached to the end. A medical procedure using any type of endoscope is called endoscopy.
Endoscopes work on total internal reflection phenomenon. Then light is transmitted back to the physicians viewing lens through the outer fibre tube by the internal reflection. Margo Schlanger, I used to be the head of the DHS civil rights office. Total internal reflection happens when a propagating wave strikes a medium boundary at an angle larger than a particular critical angle. Prisms are used in the construction of a periscope.

They reflect light from headlights from cars guiding the driver along the path.

The inner part of the fibre optics is called core that carries the light and an outer concentric shell is called cladding. Doctor can see the view recorded by the camera on a computer screen. This tutorial explains how total internal reflection takes place with real life examples in everyday life. Applications of total internal reflection video.
