The article briefly discusses the main achievements of companies in the field of creation and application of technical means intended for testing, measurement and non-destructive testing of modern structures and materials for various purposes. These are means of vibration diagnostics and non-destructive testing based on the use of various physical methods of interaction of radiation and fields with the substance and the object of control. Brief information is given about the companies that deal with these problems.

The main types of technical facilities non-destructive testing are presented. The classification of defects in rotating equipment by different indicators was made. The basic trends in development of vibrodiagnostic non-destructive testing of technical objects are described. The evolutionary model of vibration diagnostics at transition to service and repair based on the actual condition was developed.

The X-ray non-destructive testing process is carried out by the system, which includes: the object of control (OC); source of radiation; detector; operator. The X-ray radiation and the object of control interaction formed the radiation image as X-ray doze distribution in accordance with the properties of the OC. At this stage, useful information about the OK is formed, which one is partially lost, partially distorted, and veiled with noise when the radiation image is converted into an optical one. The optical image is analyzed by operator, and the result of the control depends from his physical and emotional state.This article presents a phased analysis of the entire radiation monitoring system. The first stage is the radiation image formation. Theoretical estimate of X-ray inspection system minimum detected defect size was made using space frequency spectrum analysis. The second stage is the transformation of the radiation image into an optical one. We represented the simulation of this process and obtained a modulation of how the operator sees the X-ray optical image and makes a decision about the OC state. Analyzed the X-ray digital image formation and determined the energy choice criteria when applied digital radiography.

A computer model and the results of a numerical experiment for a sensitive element on a planar mushroom-shaped metamaterial with cells of the “Maltese cross” type are presented. The proposed electrodynamic structure is shown to be applicable for nondestructive testing of geometric and electrophysical parameters of technological media, as well as searching for inhomogeneities in them. Resonant frequency shift and change of the attenuation coefficient value of the structure serve as informative parameters.

A powerful non-destructive testing (NDT) technique is adopted to study the internal defects and elemental distribution/homogeneity and porosity of aerated brick and EPS aggregate poly brick samples. In the present study the internal defects like homogeneity, porosity, elemental distribution, EPS aggregate and aerator distributor in the test samples have been observed by the measurement of gray value/optical density of the neutron radiographic images of these samples. From this measurement it is found that the neutron intensity/optical density variation with the pixel distance of the AOI of the NR images in both expanded polystyrene (EPS) aggregate poly brick and aerated brick samples comply almost same in nature with respect to the whole AOI but individually each AOI shows different nature from one AOI to another and it confirms that the elemental distribution within a AOI is almost homogeneous. Finally it was concluded that homogeneity, elemental distribution in the EPS aggregate poly brick sample is better than that of the aerated brick sample.
