This book provides an overview of infrared thermal imaging as an advanced, non-contact, and non-destructive tool in biosystems engineering. It covers the principles, systems, and methods of thermal imaging, and explores how infrared technology can be used to assess surface temperature and material properties with high precision and efficiency. Insights into image acquisition techniques, thermal data processing, and interpretation using statistical and artificial intelligence-based tools are also provided. This book further highlights real-world applications across agriculture, natural resources, and food systems — ranging from monitoring soil, plant, and animal conditions to quality control in food processing and preservation of different ecosystems. With its interdisciplinary approach, this book bridges engineering with biological systems, helping researchers, students, and professionals harness thermal imaging for improving productivity, reducing environmental impacts, and developing sustainable innovation. Suitable as a practical reference, it is an essential guide for biosystems engineers, agronomists and other agricultural professionals, food technologists, environmental scientists, and industry practitioners seeking to adopt cutting-edge imaging techniques in their work.

Dr. Digvir S. Jayas is the President and Vice-Chancellor of the University of Lethbridge, Lethbridge, Alberta, Canada. He is also Vice-President (Research and International) Emeritus and Distinguished Professor Emeritus at the University of Manitoba. He was educated at the G.B. Pant University of Agriculture and Technology, Pantnagar, India; the University of Manitoba; and the University of Saskatchewan. He completed a 11.75-year term as Vice-President (Research and International) at the University of Manitoba. Before assuming that position, he was Vice-President (Research) for two years, and Associate Vice-President (Research) for eight years. Prior to this, he was Associate Dean (Research) in the Faculty of Agricultural and Food Sciences, Head of the Department of Biosystems Engineering, and Interim Director of the Richardson Centre for Functional Foods and Nutraceuticals (now Richardson Centre for Food Technology and Research).  He conducts research related to drying, handling, and storing cereal grains, pulses, and oilseeds and digital image processing for grading and processing operations in the Agri-Food industry. He has collaborated with researchers in several countries and has had significant impact on the development of efficient grain storage, handling, and drying systems in Canada, China, India, Ukraine, and the United States. He has authored or co-authored over 1000 technical articles in scientific journals, conference proceedings, and books dealing with issues of storing, drying, handling, and quality monitoring of grains and foods. He was the recipient of the 2017 Sukup Global Food Security Award from ASABE, and the 2008 Brockhouse Canada Prize from NSERC. In 2009, he was inducted as a Fellow of the Royal Society of Canada (RSC) and in 2018, he was appointed as an Officer of the Order of Canada for “his advancements to agricultural practices worldwide, and for his promotion of academic and scientific research in Canada”. In 2022, Dr. Jayas was inducted into both the Manitoba Agricultural Hall of Fame and the Canadian Agricultural Hall of Fame in recognition of his engineering contributions to grain preservation. In 2023, he received the John Deere Gold Medal from the ASABE and the Lieutenant Governor’s Award for Excellence in Public Administration, Institute for Public Administration Canada (IPAC) - Manitoba. In 2025, was invested in the Order of Manitoba. He has served as the President of the Agriculture Institute of Canada, the Canadian Institute of Food Science and Technology, the Canadian Society for Agricultural and Biosystems Engineering, Engineers Canada, Engineers Geoscientists Manitoba, and the Manitoba Institute of Agrologists. He chaired NSERC Council; the board of directors of TRIUMF; the board of RESOLVE, a prairie research network on family violence; and the Smartpark (University’s Research and Technology Park) Advisory Committee. He is currently serving as Chair of CAF-PC and President of AZRA.

Dr. Kamran Kheiralipour is currently serving as faculty member in Mechanical Engineering of Biosystems Department, Ilam University, Ilam, Iran. He completed his bachelor’s degree from Ilam University, Ilam, Iran, and obtained his master’s and Ph.D. degrees from the University of Tehran, Iran. He has worked on thermal, hyperspectral, and visible imaging during his doctorate and later in collaboration with different researches and published several papers on the field of applications of imaging in biosystems engineering. His current research interests include visible, thermal, and hyperspectral imaging. He has served as General Manager of Student Affair in 2013, Dean of the Technical, Engineering, and Agricultural Junior College (Dehloran Campus) in 2017-2022, and Research Deputy of Agricultural Faculty in 2023-2025.
