Microbolometers: Fundamentals, Materials, and Recent Developments describes the fundamentals of microbolometers, their historic evolution, operational principles and material choices. It also explains the impact of materials on the processing and development of device characteristics. Sections address various aspects of optical properties and recommend models of properties of materials of interest for the fabrication of the uncooled microbolometers. In addition, the book presents two case studies, Honeywell and Texas Instruments, that focus on the design and manufacture of microbolometers.
Finally, recent developments, applications, patents and future trends are presented. The chapter on patents will summarize the strengths and weaknesses of each of the technologies.
- Describes the fundamentals of uncooled infrared detectors, operational principles and material approaches
- Includes case studies based on Honeywell and Texas Instruments' work on microbolometers
- Provides analyses of current patents with a look towards their strengths and weaknesses
