MEASUREMENTS OF THE STATISTICAL CHARACTERISTICS OF THE TURBULENCE OF AN OPTICAL SYSTEM WITH HYBRID FIBER-OPTIC SENSOR

摘要

An optical system for diagnostics of turbulence with hybrid fiber-optic sensor is considered. The system functions in a digital mode of photographic recording of a two-dimensional accumulated optical signal directly associated with the two-dimensional probability density of turbulent fluctuations of the flow in the measurement region. From the values of the probability density, estimators of the statistical characteristics of turbulence are given in the form of digital matrices.
