What do you ned to know about emerging thermal camera technology and SWaP-C for dual use applications?
How can SWAP-C Principles Enable Inexpensive High-Definition Thermal Imaging Cameras?
Compact thermal cameras are suitable for applications involving automated inspection, autonomous vehicles, drones, and monitoring of production equipment.
Two considerations drive the selection of cameras for volume applications—performance and the burden on resources including limits on accommodating size, weight, power, and cost. For visible-band cameras, both monochrome and RGB, the demands of their highest volume applications—machine vision, surveillance, mobile phones—have driven the performance up and the total resource burden down.
Until recently, no application has placed similar demands on thermal cameras operating in the long-wave infrared (LWIR) band, but now, with the mandate from the U.S.National Highway Traffic Safety Administration (NHTSA) requiring all 2029 cars to include day/night automatic braking, the need for high performance, compact thermal cameras has become urgent.
Thermal imaging has been available for almost 100 years, beginning with a two-pixel camera in 1929, cooled line-scan sensors in the 1960s, cooled area arrays in the 1970s and uncooled microbolometer arrays in the 1980’s. Today, the highest-performance thermal cameras (and most expensive) are cooled but smaller and cheaper uncooled cameras make up the vast majority of units in service.
Even so, the cost of uncooled cameras is tightly tied to performance. The two most important factors are spatial resolution—the number of pixels in the array—and temperature resolution— the smallest difference in temperature in the scene that can be discerned. The variation in requirements for particular applications is substantial.
