We investigate the problem of metrologicaly low capabilities of the analog gauges on the basis of fiber-optic sensors (FOS) as well as analyze the reasons and justify the transition to the pulse (discrete) principles of modulation parameters of the optical flow in FOS. For this purpose, the additional, non-optical parameters, which shifted the role of recipient of information, and from which this information may be reproduced with the required accuracy, could be added to the optical flow. The schematic of a FOS design is developed. Metrological calculation of linear acceleration meter based on IFOS is performed and discussed.
