OSE6242 - Infrared Systems

This course focuses on the measurement of infrared light and its spatial, temporal and spectral characteristics. First, the course introduces radiometry—a set of methods for measuring electromagnetic radiation—and defines radiometric quantities and units of measurement. Next, we will study the theory of blackbody radiation and concepts such as shot noise and Johnson thermal noise, all of which limit the signal-to-noise ratio of infrared detection. Finally, we'll cover a variety of infrared detectors, from photodiodes to superconducting single-photon detectors, and to focal plane detector arrays.
