Optical Fiber Endoscope

Ideas for science assignment?

I need to choose one topic out of four suggestions to complete my physics assignment on. They are;
1) Optical Fibre Technology
2) The Astronomical Telescope
3) The Endoscope
4) Digital Cameras

Any suggestions on what to choose, and why or why not?
I don't really know much about any :S
Any info or websites relating to the topics would be great

Thanks.

Endoscope is easiest. Optical fiber is a better choice as you can throw in some good physics. Digital cameras and astronomical telescopes offer a lot of scope (sorry) but you might spend too long on your preparatory readings.

Optical Fiber Communications, 4th Edition $113 The fourth edition of this popular text and reference book presents the fundamental principles for understanding and applying optical fiber technology to sophisticated modern telecommunication systems. Optical-fiber-based telecommunication networks have become a major information-transmission-system, with high capacity links encircling the globe in both terrestrial and undersea installations. Numerous passive and active optical devices within these links perform complex transmission and networking functions in the optical domain, such as signal amplification, restoration, routing, and switching. Along with the need to understand the functions of these devices comes the necessity to measure both component and network performance, and to model and stimulate the complex behavior of reliable high-capacity networks.

Specialty Optical Fiber Technology for Optical Devices and Components (Hardcover) $236.12 As the emphasis in optical fiber research expands from transmission media to functional fiber devices, various types of specialty optical fibers are being actively developed. Especially in dense wavelength multiplexing (DWDM) systems, novel functions such as fiber filters, fiber MUX/DEMUX, fiber amplifiers, among others, are constantly needed and supplied by specialty fibers. Until recently, optical fibers were treated as passive transmission media with very little attention given to these novel fiber technologies.

J300 36inch Endoscope

Can you help me with this physics problem?

You are designing an endoscope for use inside an air-filled body cavity. A lens at the end of the endoscope will form an image covering the end of a bundle of optical fibers. This image will then be carried by the optical fibers to an eyepiece lens at the outside end of the fiberscope. The radius of the bundle is 1.00 mm. The scene within the body that is to appear within the image fills a circle of radius 6.60 cm. The lens will be located 5.87 cm from the tissues you wish to observe.
(a) How far should the lens be located from the end of an optical fiber bundle?
_______mm
(b) What is the focal length of the lens required?
_______ mm

Good luck with this one Dude....there's a reason my degree was in History!
