Thermal imaging
Thermal imagers are electro-optical imaging systems sensitive to mid-wave and long-wave infrared radiation that generate images of the observed scenery using thermal radiation emitted by the scenery. They have found numerous applications in both defence &security sector (military, border guards, police, etc.) and civilian sector (industrial non-contact temperature measurement, non-destructive thermal testing, tests of electrical power lines, building industry, medical applications, fire rescue etc.)
Testing thermal imagers is a very difficult task. Extended knowledge from different areas like physics, optics, electronics, thermal sciences, precision mechanics, metrology and practical experience with thermal imagers is needed to carry out effectively testing modern thermal imagers. There is rich literature on the subject of testing and evaluation of thermal imagers and there are also several standards that regulate tests of these imaging systems. However in spite of available standards, valuable books and numerous literature less experienced test teams have a lot of problems to carry out their tasks due to lack of a practical guidebook in field testing thermal imagers.

In this educational section the book
Review of
thermal imaging technology
written by Inframet CEO
and published in year 2024 is offered. The book presents complete technical review of main EO imaging technologies (thermal imagers, night vision devices, VNIR cameras and SWIR imagers) and gives answer to a series of fundamental questions: 1)how are designed/manufactured, 2)how blocks are built, 3)what is technical division, 4)what are future trends. The book has been published by INFRAMET as e-book (ISBN number: 978-83-972882-0-1) and shall be distributed as free open access publication. This book is a free gift of INFRAMET to a wide international community of people interested in this fascinating technology. In this way INFRAMET had becomes not only a commercial company (manufacturer of test systems) but also a non-profit publisher sharing it know how in field of EO technology. Reading of this book is recommended for anyone interested in thermal imaging, and especially for beginners to this technology. |

Image is often worth more than thousand of words. Therefore a visit to another section of this website that presents computer simulators developed by Inframet is recommended. These are computer programs that simulate an imaging system by generating on computer screen images similar to images generated by the simulated imaging system.
