The most excellent solution to this problem is the fiber-optic Sagnac interferometer. I read several years ago that a French group had microfabricated a fiber-Sagnac sensor, but I don't know the status of the work at this time. The reason that the technology is so exiting is that the reference has 1) no moving parts 2) potentially awesome sensitivity and accuracy and 3) is small. More info on the basic method (used by Michelson to measure the earth's angular velocity) can be found in Hecht and Zajac, "Optics", Addison-Wesley, pp323.
