Fundamentals of mathematical analysis, physics, general, inorganic and organic chemistry are prerequisites to understand the course topics.
The final examination consissts of an interview on the topics covered by the front lections.
Knowledge of the physical, chemical, physiological and psychological fundamentals of human chromatic perception.
Measurement of colour.
Chemistry of dyes and pigments.
Fundamentals of technological application of dyes and pigments.
Ray optics: reflection and refraction.
Wave aspects of light: electromagnetic waves, interference, diffraction, scattering. Absorption and emission of photons by matter. Light sources and illuminants. Radiometry.
The eye and vision: Structure of the eye. Retina: structure and functioning. Day and night vision: rods and cones. Transmission of the signals to the brain. Colour vision and colour blindness. Photometry.
Colorimetry: Tristimulus values. Illuminants. Colour spaces. CIE standard colorimetric system. CIE diagram. Metamerism. Measurement and calculation of colorimetric values. Uniform colour spaces. Empirical colour spaces. Instruments for colour measurement. Technological applications.
