In Chapter 11 we divided resonator gyros into active and passive types, and in Chapter 13 we described active ring laser gyros, RLGs. Now we describe the passive resonator gyros, which can be made from either “free space” optics—lenses, mirrors, and other discrete components—or from guided wave optics—fibers or integrated optics, waveguides, and thin film devices. The free-space type might use an empty RLG-like block with mirrors on it, while the guided wave type can use an optical fiber resonator or an integrated optics resonator in which waveguides are formed into an optical chip. We shall look at each in turn, and then we’ll compare them.
