Radiometry

22 Setembro 2022, 14:00 • José Manuel Rebordão

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.

Presentation of the course

19 Setembro 2022, 10:00 • José Manuel Rebordão

Introduction to the course. Information available on Fenix. Contents (T). Laboratory work. Assessment. Background material from other courses, namely Electromagnetic Waves and Optics (2^nd year, 1EF) and Fourier analysis (series and integral transform).

What can be measured when dealing with optical beams: optical observables of 1^st order (beam geometry, spectrum, phase, amplitude and polarization) and 2^nd order (correlation functions, coherence). Main architectural options of optical systems.
