Zaitsev E. Self-correcting electronic converters for laser movements and vibrations measuring instruments

Object of research: pulse, phase and frequency-phase laser range finders. The purpose of research: development of methods to improve accuracy and speed, sales on the basis of their high self-correcting electronic transmitters for pulsed phase and phase-frequency laser gauges linear displacement and vibration parameters. Methods of research: numerical simulation using a personal computer, methods of probability theory and mathematical statistics, theory of measurement errors, the spectral-correlation theory of stationary random processes, elements of the theory of automatic control systems, theory of optimal filtering. Theoretical and practical results: first developed a method to choose the desired value, the sampling frequency of the characteristics of the used filters and low noise influence, first proposed and justified a system of adaptive noise compensation in conjunction with the Hilbert transform to the phase of the laser system measurement of vibration, developed a method for correction of errors due to instability the amplitude and the influence of spatial and temporal heterogeneity of the modulated laser beam in pulsed systems using the least squares method for the optimization of the experimental features, the first time the technique of estimating the frequency of "rough" for the frequency-phase systems, based on the evaluation of the center of symmetry with regard to the equality of areas of squares spectral component, proportional to the measured distance, made a synthesis of the optimal filter to reduce the influence of random errors allowing for the construction of a frequency-phase systems.Degree of introduction: use of " УкрНДГМІ " for the measuring software the height of the lower boundary of the clouds "Примінь" and stands in the laboratory parameters of vibration measuring instruments in the Institute of Electrodynamics NASU. Sphere of use: automation and contact control of technological processes in metallurgy, power and other industries.
