摘要：
The article reviews the capabilities and particularities of the approach to the improvement of metrological characteristics of fiber-optic pressure sensors (FOPS) based on the dynamic reflexive transformation method. It is shown that this method applied to the metrological characteristics allows for the minimization of measurement errors. It is found that when using this method a dynamic correction element gets involved in the output of a photocurrent converter, having unstable dynamic properties; the dynamic characteristics of the correction element are maintained automatically in specified accordance with current condition of the dynamic characteristic of the photocurrent converters. It is shown that, in case of fiber-optic pressure sensors being different by significant nonlinearity of the transformation function of "laser - feeding light guides - membrane reflector - branching-off light guides - photoconverter" unit, the reflexive transformation algorithms are appropriate to be included in the algorithms for the photoconverter data processing.
