Microscaner based on synchronous motor for third generation thermal imagers

Formulation of the problem. The use of FPU matrices, with the maximum achievable resolution, does not leave the desire to increase the detail of the final image, which is dictated by the main tasks set for thermal imaging technology: increasing the object detection range and increasing the object recognition range. It is obvious that in the race for the competitive advantage of the final product, in the conditions of reaching the technological limit of the basic elements (FPU matrices, etc.), additional methods are needed [1, 3] and devices. The analysis of existing systems allowing to increase the resolution of thermal imagers is carried out. The physical principles of construction and the predominant differences of microscanning devices (MSD) are considered. A prototype MSD based on an external rotor engine was made. The results of testing the device and its operational characteristics are presented. The simplicity of the design of the MSD and its low cost make it possible to expand the capabilities of thermal imaging equipment: the detection range and / or the recognition range of scene objects are increased.

Development Trends of Infrared Focal Plane Array Detectors

Since its inception, the market for infrared (IR) thermal imaging equipment has grown, primarily, due to its military applications. Today, the military sector still provides some growth for the market, but its development paradigm has changed. Now the main growth in the market is provided by the sectors of civil and medical thermography, security and fire surveillance, personal night vision systems and local security niches (municipal, private, etc.). The devices using thermal imagers make it possible to detect in conditions of poor visibility, to detect people with high temperature in the crowd. In the last decade, a number of new directions and trends have been outlined in infrared photoelectronics. They are associated with increasing the resolution of systems, improving methods for recording ultra-weak optical signals, creating high-speed and multispectral systems, forming infrared 3D images According to forecast of Maxtech International (USA) and today's estimates of the authors, the market for infrared systems (civil and military) amounted to 10.5 billion dollars in 2017, and could reach 20 billion dollars by 2025. Due to the pandemic, we have restated the Maxtech International's forecasts upwardly for the medium term.

APPLICATION OF ACTIVE AND PASSIVE THERMAL CONTROL IN DEFECTOSCOPY OF CONSTRUCTION MATERIALS AND PRODUCTS, FILLER STRUCTURES OF BUILDINGS AND CONSTRUCTIONS

one of the perspective and modern methods of nondestructive testing – thermal control is considered. The possibilities and advantages of thermal control in the identification of defects in various building materials and products, enclosing structures of buildings and structures are given. The short characteristics of the main defects of building materials and products, buildings and structures are proposed. The basic principles of identification of hidden (invisible) and obvious (visible) defects are briefly considered and practical results of construction flaw detection of objects for various purposes with the use of thermal imaging equipment are presented. On the example of a fragment of the enclosing building structure of piece building products in the form of ceramic bricks with artificially created technical defects in the process of qualitative analysis of thermograms zone of thermal temperature anomalies (method of active thermal control) are localized. For some enclosing structures of buildings and structures based on the results of thermal imaging identified obvious thermal defects, their qualitative analysis and recommendations for elimination (method of passive thermal control) are made.

USE OF THERMAL IMAGING IN CONSTRUCTION

Thermovision is a research method based on non-invasive and non-contact evaluation of temperature distribution on the surface of the examined body. These methods are based on observation and recording of the distribution of infrared radiation, sent by each body whose temperature is higher than absolute zero (-273C) and visualization of the temperature field by thermal imaging equipment. In construction, thermovision is used to assess the quality of materials used in construction, structural solutions and the quality of construction work. With its help we can locate, for example, thermal bridges, which are the result of improperly made or damaged during the operation or installation of thermal insulation. Detection of thermal bridges helps to reduce the amount of fuel used and thus save on the costs of heat energy. Using thermal imaging it is also possible to assess the condition of heating pipelines (damage to insulation, corrosion, location of leaks), control heating devices such as: heat substations, radiators. The subject of the study is to show examples of how thermal imaging is used and useful in construction.

THERMOVISION METHOD OF DETERMING THE MOISTURE FIELDS OF BUILDING SURFACES OF CONSTRUCTION STRUCTURES OF BUILDINGS AND CONSTRUCTIONS

The current issues of excess heat losses by construction projects are identified and analyzed. It is established that the heat loss of buildings depend on the thermal qualities of external building structures of different materials, the main of which are density, humidity, thermal conductivity. In this regard, practical methods for identifying temperature and humidity fields of the surfaces of building structures in the mode of their operation are of particular importance. The technical capabilities of modern thermal imaging equipment for obtaining and processing thermograms of thermal imaging of the controlled object are presented. A practical example of thermal definition and analysis of temperature and humidity fields of translucent enclosing building structures in the form of a window in a window opening is given. It is confirmed that thermal imaging diagnostics is able to state the distribution of heat losses in the control zone. On the basis of this knowledge, measures are developed to reduce them (alignment) and subsequently assess the effectiveness of their implementation
