The aim of this diploma project is to develop a portable thermal imaging system designed to visualize the spatial distribution of thermal radiation of objects in real time and to detect temperature anomalies.
The work includes an analysis of the physical principles of infrared radiation, justification of the choice of an uncooled microbolometer array MLX90640 and a powerful dual-core ESP32-S3 microcontroller with additional external memory. The system architecture has been developed, an electrical schematic has been designed, and software for data acquisition, filtering, and temperature data processing has been implemented. Two-dimensional interpolation algorithms have been realized to improve the visual resolution of thermal images and to generate pseudo-color images on a TFT display.
The power consumption of the system has been calculated, and a standalone power supply unit based on lithium-ion batteries has been developed. The device enclosure has been designed and manufactured using 3D printing technology, taking into account ergonomics and protection of electronic components. A working prototype of the device has been built and its functionality has been confirmed through experimental testing.
The thesis consists of 5 chapters, 55 figures, and 41 references.
