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 TESTING THERMAL IMAGERS written by Inframet CEO and published in year 2010 is   offered. 
This book presents knowledge of the author on testing thermal imagers that was accumulated during over two decades of scientific work in the field of electro-optical technology interconnected with a series of practical projects, and direct involvement development  of equipment for testing thermal imagers. The author hopes that this book can become a practical guide for testing thermal imagers for wide community of people interested in this fascinating technology of thermal imaging.
Nowadays,  the part of  this book that refers to test equipment is outdated.  However information on parameters definitions and tests methods is still fully valid.  Therefore reading of this book is recommended  for anyone interested in thermal imaging, and especially for beginners to this technology.
Other recomended readings on thermal imaging metrology:
  1. Chrzanowski K, Evaluation of infrared collimators for testing thermal imaging systems, Optoelectronics Review, Vol. 15, No 2, 82-87, 2007.

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.
