This monograph is dedicated to the 125th Аnniversary of the establishment of the Igor Sikorsky Kyiv Polytechnic Institute. For more than 100 years of its existence, this university has formed dozens of world-renowned scientific schools and developed hundreds of scientific areas. Among them, a prominent place is occupied by research on the creation of precision systems and technologies. The monograph reflects some of the results obtained at the Igor Sikorsky Kyiv Polytechnic Institute in this field. The chapters of the monograph are grouped into three areas: optoelectronic technologies, medical technologies, and technological support.

The first chapter is devoted to some topical issues of optoelectronic instrumentation development. A model of signal transformations in thermal imaging observations is considered, on the basis of which methods for calculating the spatial and energy resolution of thermal imagers are proposed. The methodological bases of improvement of multichannel optoelectronic systems of remote observations with image fusion are proposed. They include methods of constructive coordination of the characteristics of the system units, a mechanism for adaptive selection of the best way to combine spectral images, and means of experimental determination of the main characteristics of the system. It is shown that the developed specialized software with modern global optimization algorithms can automate the optical design process. In particular, this approach has been successfully tested in the design of various optical systems with constant and variable parameters.

The second section is devoted to systems and methods for analyzing the state of biological objects and their modeling. In particular, a new method of photometric analysis for simultaneously taking into account the optical properties of biological media in reflected and transmitted light in a full body angle is presented, and circuitry and technical variants of the information and measuring system of spatial photometry are given. The prerequisites for the manufacture and use of ellipsoidal reflectors in light scattering detection systems, research and testing of new constructive, functional and biomedical solutions are characterized. The theoretical foundations and principles of research into the creation of automated testing systems for alternating magnetic field devices are outlined. The peculiarities of creating a myographic system of a wrist prosthesis with enhanced capabilities of movements and gestures based on the recognition of myoelectric signals by the neural network interface and an optical identifier of the contact surface of the fingers are presented.

The third section deals with issues related to various aspects of automation of determining the state of complex objects and their management. The results of the development of a new methodology for vibroacoustic monitoring and diagnostics of initial damage to elements of rotating systems in steady-state and nonsteady-state operation are presented. Initial crack-like damages of rotor blades and shafts are considered. On the basis of theoretical studies, computer and physical modeling of vibroacoustic processes, and the use of effective methods of diagnostic information processing, diagnostic signs of damage are determined. The studies have confirmed the effectiveness of the proposed methodology.
