laser gyroscope
I just deleted:
"External link:
This article discusses some specialized detail of laser gyros. It is certainly of no interest for anybody who read this article in order to find out what a laser gyro is. Simon A. 07:45, 24 Jun 2004 (UTC)
The text says " The angular position is measured by counting the interference fringes". Is this really correct? Can the device really directly measure angular position? Isn't that an impossibility? Doesn't it rather measure angular _velocity_, and not position (then integrating the velocity over time to yield the angular position)?
Yes. It measures absolute position exactly that way. Dennis 03:50, 30 Jan 2005 (UTC)
First paragraph mentions a "bulk optic ring", isn't this referring to the other type, the fibre optic gyro which used a long fibre cable coiled into a ring? --Kjw 00:10, 20 February 2006 (UTC)
This page really needs more links, there is nothing to back up the text. This is annoying as the information is good, but cannot be quoted as a reliable source. Thanks, Sam Mcmadkat 11:54, 25 May 2007 (UTC)
[edit] Error
This article doesn't properly distinguish between the fiber gyro which IS a direcct application of the Sagnac effect (and works exactly the way described, but with multiple turns) and the much more sensitive LASER gyro which is incorrectly described. Anyway I'll change those parts. (soon) —Preceding unsigned comment added by 82.95.146.159 (talk) 22:35, 23 January 2008 (UTC)
