Syllabus
1. Introduction of basic radiometric concepts: radiation energy, radiant flux (power), irradiance, radiant intensity and radiance. Introduction of corresponding spectral quantities. Introduction of corresponding photometric and actinometric quantities.
2. Isotropic source (radiator). Cosine (Lambertian) source. Relationship between irradiation and radiance for a cosine source. Relationship between irradiance and radiance for a point sources. Approximation of a point source and detector. Validity of point and cosine source approximation.
3. Radiant flux transfer equation in a homogeneous and isotropic environment. Theorem of a radiance conservation in a lossless environment. Elementary solution of the radiant flux transfer equation and its application.
4. Optimization of radiant flux transfer from a source to detector in optical systems. Approximations used for centered systems, numerical aperture and F-number.
5. Absolute measurement of optical radiation. Absolute sources: black body, synchrotron radiation, calibration of other radiation sources. Absolute detectors: thermal detectors, actinometers, detectors with predictable quantum efficiency.
6. Imaging defects (aberrations), Abbe's sine condition. Limits of radiation concentration; maximizing numerical aperture by immersion. Integration sphere and the principle of its function.
