Applications of optical fibers in astronomy

[alfu]

I'm doing a presentation in this topic and I find it very hard to look for information on the web. Please, point me to any website or resources that have information about this topic? Thank You~!

Here is a link to the 2 degree field galaxy redshift survey. The largest redshift survey to date with around 220 000 galaxy redshifts with median redshift ~ 0.1 and an average magnitude limit of 19.45.

The 2df instrument uses ~400 optical fibres to take spectra of galaxies spread over 2 degrees of sky in one pointing.



The 2df instrument is now being decomissioned and is to be replaced by AAOmega, which will have higher sensitivity.
