A block diagram of a laser measuring system with a fiber-optical sensor for monitoring the air gap between the rotor and stator of a hydrogenerator has been developed and analyzed. The system uses an algorithm for alternating comparison of the investigated and reference light fluxes. This makes it possible to reduce the influence on the measurement result of the gap of the instability of the parameters of individual units and blocks of such a system. The analysis of the main measurement errors, which can affect the result of determining the gap, is carried out. References 16, figure 1.

Light transmission in the reflection fiber system, located in external optical media, has been investigated for application as sensors. The system was simulated by different models, including external cavity parameters such as the distance between light emitting and receiving fibers and mirror positioning distance. The sensitivity to a linear displacement of the sensors was studied as a function of the distance between the tips of the light emitting fiber and the center of the pair reflected light collecting fibers, by positioning a mirror. Physical fundamentals and operating principles of the advanced fiber optical sensors were revealed.
