fibre optic gyro

fibre optic gyro.........as in gyroscope.

I have heard about 20 + years ago about ???? developing a gyroscope base on lights wave length.......for future long distance travel (Light years).

They use optical gyros in both missiles and airplanes. However, the last I heard the technology was classified.

Back in the days when I was working with fiber optic gyroscopes, most of the systems were classified, but today there are a few companies selling them on the open market. Try EADS Atrium. A Google search will generate a lot of references (about 107,000), some of which may help with the testing aspects. It would seem there are a number of companies out there trying to commercialize these units...

FOG's are coming into mainstream navigation for several reasons. first, they are highly accurate, around 0.1 degree of secant or better. Second, they are nearly instant-on compared to a conventional gimbaled gyroscope that takes a lengthly period of time to north-seek and settle. It is important that a FOG have GPS data available to it so that it knows where it is, i.e., latitude, speed, rate of turn. But, this is not normally a problem as a gyro is usually supplying True Heading to an integrated navigation system.

There are several manufacturers of FOG's. IXSea, of France is one of the better FOG's. Their website contains an abundance of information. Just do a web search.

Be advised, FOG's are still Very expensive!

r u really a student? then can you tell where are u studying please.i recommand Dr Rathakrishnan of cusat ,kerala india for your search .he can help you.www.cusat.com .photonics department.ok
