SPIE - Education Infrared Imaging Radiometry with Applications to Target Measurement SC950

This course will enable the user to understand how an infrared camera system can be calibrated to measure radiance, radiant intensity and apparent temperatures of targets and scenes, and how the camera’s digital data is converted into radiometric data. The user will learn how to perform their own external, "by hand" calibrations on a science-grade infrared camera system using area or cavity blackbodies and an Excel spreadsheet provided by the instructor. The influences of lenses, ND and bandpass filters, windows, emissivity, reflections and atmospheric absorption on the system calibration will be covered. The instructor will use software to illustrate these concepts and will show how to measure emissivity using an infrared camera and how to predict system performance outside the calibration range.
