Research of the physical, technological and informative principles of creation of electronic devices, built on in industry of the physic-technical and informative systems executed in the five directions. In the first part of the work there was conducted the analysis of modern non-contact control systems and measuring the level of liquid corrosive melts and the main requirements for the ways and means of processing of the quasi-stationary stochastic optical signal to improve the accuracy and reliability of the process control of melting glass were determined. Were proposed and implemented the methods for processing quasi-stationary stochastic optical signal which passes through the high optical environment, is reflected from the melt surface and is recreated on the screen, from which, through the lens, the laser spot image on the photosensitive matrix of CMOS image sensor. There were determined the advantages of CMOS image sensor as a detector of laser radiation. It was conducted a physical-mathematical modeling of proposed algorithms of digital treatment of quasi-stationary stochastic optical image of spot of laser radiation that allowed to calculate the control characteristic of non-contact laser level meter. The laboratory prototype of technical vision specialized system for control of level of the melt surface and automatic control of glass melting furnace loader was developed and implemented. In the second part of the work a design was proposed for an evanescent-wave laser TV ultra-microscope that can be used for observation of micro- and nanoparticles; experiments conducted for estimation of the ultra-microscope parameters were described. A design of a laser projection ultra-microscope is developed, which allows to observe on the screen micro- and nanoobjects with magnification over 2000x and conduct their measurement. A theoretical justification is provided for the possibility of overcoming of the Abbe limit of ?/2 for optical microscopy by using interference between the object waves from two closely-positioned point sources and the reference wave of an additional point source positioned on the same axis, at a distance much larger than ?. In the third part of work was provided the analyzing of physical and technical basis of building the sensors, based on surface acoustic wave (SAW). It is shown, that SAW-sensors are based on such physical effects: changing of phase velocity and acoustic length of SAW delay line as a result of acoustic-line deformation; changing of phase velocity of SAW with removing the mechanical probe in the wave electric field; changing of acoustic length of delay line with removing of moving SAW receiver over the surface of piezoelectric acoustic-line; changing of phase velocity of SAW with action of environment factors (such as temperature, humidity, electric fields etc.) to the acoustic-line material; changing of frequency characteristics of delay line with deposition of additional mass to the acoustic-line surface. The physic-mathematic model of sensors of physical values, based on analyzing the distribution of electric field in SAW, is elaborated and investigated. The possibility of using the dispersion of SAW phase velocity, taking place with removing of mechanical probe in the wave electric field, for building the sensible elements of micro displacement, force and pressure, have been grounded theoretically. Physic-mathematical model allow calculating the range of measuring, sensibility and resolution of sensors for known design factors. Using of differential circuit and frequency output signal reducing remarkably the influence of destabilization factors. Changing of acoustic-line design factors, inter digital transformers, membrane, allow creating the sensors with required metrology parameters. The construction of passive wireless SAW sensor for measuring the temperature and humidity, based on using the thermo resistance, disposed in the controlled environment, as well as mathematical model of this construction, are proposed. As a result of using such construction by forming the reference signal and by removal the influence of environment to the acoustic-line surface, the accuracy of measurement is increased. In the fourth part of this work the classification of modern radiation non-destructive testing systems is presented, a detailed review of these systems has been performed and their properties, advantages and disadvantages has been analyzed. It has been shown that the most promising are X-Ray television systems with indirect conversion "scintillator CCD". Several digital X-Ray television systems "scintillator CCD" has been developed. Experimental research of developed systems has been made during translucence of real industrial objects. The mathematical model of transformation of X-Ray images in X-Ray television systems such as "scintillator CCD" has been developed as well as physical and topological models of pulsed X-Ray tubes with reflective and transmissive anodes. Instantaneous and total energy spectra of pulsed X-ray tubes with reflective anodes and the direction diagrams of pulsed X-ray tubes with transmissive anodes has been calculated. The use of pass-through coefficient of spectral matching has been proposed, which characterizes the coordination of all elements of the pulsed X-Ray television system, which are included in X-Ray part and in optical part. The fifth section performed the research and development of prototypes of vacuum and plasma physical and technological devices for coating and surface treatment. There was developed and tested a method of constructing a hierarchical set of physical-topological and mathematical models of induction evaporators, which constitute the scientific basis of the simulation of advanced induction evaporators for the deposition of coatings and produce thin films. A reaction deposition of thin aluminum films with a developed surface in an environment of low pressure oxygen by electron-beam evaporation of aluminum with the ionization of aluminum vapor and oxygen in a pulsed inductive HF discharge has been proposed and investigated. The magnetron sputtering device for producing and studying the properties of nickel aluminide films has been designed. The device provides a simultaneous sputtering target of non-magnetic material (Al) and of magnetic material (Ni), of which the magnetic pole pieces were made of. It was designed and investigate the source of uniform flat flow non-thermal equilibrium plasma of argon through the barrier HF discharge of atmospheric pressure, which can be used in processes of etching and deposition of thin films at atmospheric pressure, in the processing of polymeric materials and for the research purposes.
