The MM device does rotate sitting on a rotating Earth globe. It is not a translational movement. It can be seen as part of a Sagnac interferometer going around the globe. David On Sun, Jun 24, 2012 at 11:59 PM, Terry Blanton hohlr...@gmail.com wrote: The MM device does not rotate, right? T

Thanks for this reference. I thought lock in was also present in a optical fiber gyroscope or any type. Now I realize that the differences are big between different types of interferometers. Are you sure it is not involved in other types? What do you base your conclusion on that it isn't involved
