Description
Summary:The similarities and differences between acoustic and magnetic surface waves as compared with light waves are discussed. This comparison suggests several advantages of surface wave ring interferometers over optical ring interferometers for rotation sensing. The primary advantages are increased sensitivity, ease of construction, and size reduction. Proposed designs for such sensors are given. In the appendixes the optical ring interferometer and ring laser are reviewed. (Author)
