The width of a human hair is the thinnest endoscope

As a human hair and is four times that of similar devices with a resolution thin, scopes and other parts of the world slimmest endoscope can not reach may soon see.

Endoscopes are used to look inside the body, and are usually a bundle of fibers that transmit light and images is. Joseph Stanford University,
California, in Khan and his colleagues have now created, only out of an optical fiber. Usually when a team struggles fiber light signal reconstruction algorithm developed images.

Currently, the prototype can display items 2.5 micrometres in size - one-third of the diameter of a red blood cell - but reckons 0.3 micrometres team will be able to improve resolution.

endoscope to examine brain activity in minute detail or cancer cells (Optics Express, doi.org / ktc) can be used for detection.

As the telecom industry through optical fiber about is devised ways to squeeze more information on content, this team is for medical Endoscopy, "University of Illinois at Urbana Champaign Stephen Boppart said.
