INFRARED CAMERAS Research Experience for Teachers Paul Longwell Summer 2004

What is special about an Infrared Camera? Our eyes use visible wavelengths to create images. An infrared camera is sensitive to wavelengths that are longer.



Same Object – Different Images!



Infrared Imaging Begins With Bolometers…

Each bolometer helps form one pixel of an image…



A typical array of bolometers contains 240 rows and 320 columns



Once assembled, the bolometer array can be put in a camera.



An infrared camera requires an infrared lens!



Need a small IR camera?



This is truly a cool camera! This camera’s detector must be kept cold with liquid nitrogen!
