Distinction between radiometry and photometries. Historical background, application areas, dynamic ranges.
Analysis of the generic radiometric configuration: sources, targets, background, media, instrument detector; emission, scattering, absorption; geometry; T-dependent blackbody emission and noise levels. Optical channel between target and instrument
Solid angles, stereo-radian.
Radiometric quantities (integrated and spectral): radiant flux, intensity, radiance, irradiance, emittance. Units. Dimensions.
Dimensions of the Poynting vector and Irradiance.
Electrical signal generation (at detector level) from irradiance (at image plane level) – simple model.
