Endoscopy refers to medical examination
of the inside of a human body by means
of inserting a lighted optical instrument
through a body opening. Fiberscopes
operate in the visible wavelengths and
consist of two major components. One
component consists of a bundle of fibers
that illuminates the examined area,
and the other component transmits the
images of the examined area to the eye of
the physician or to some display device.
Investigate the design of fiberscopes or the
fiber-optic endoscope, and discuss your
findings in a brief report.
